  • Experiment 8 Thermochemistry This Week In
    Experiment 8 Thermochemistry CH 204 Fall 2006 Dr. Brian Anderson What is Thermochemistry? The study of heat in chemical reactions. Forming chemical bonds releases energy. Breaking chemical bonds requires energy. How much energy? Depends on the bond. Add up all the energies to get the heat of reaction, ∆Hrxn . This week in lab We will measure the amount of heat given off by 50 ml of hot water, by some chunks of hot metal, and by two chemical reactions + 2+ Mg + 2H → Mg + H2 + heat + 2+ MgO + 2H → Mg + H2 O + heat We’ll do all these reactions in a coffee cup calorimeter. 1 The basic operation of calorimetry - Start with a known volume of a solution in the calorimeter. - Drop in something hot, or start a reaction that generates heat. - Close the calorimeter and measure the increase in temperature as heat is generated. - Keep measuring the temperature until it finally levels out. Part One: Add hot water to cold 50 mL of cold water (5ºC). Add 50 mL of hot water (75ºC). Final temp should be (75 + 5) ÷ 2 = 40ºC But the final temp will actually be lower than that because the cup itself will absorb a little bit of the heat. Heat Capacity We will use the data in part 1 to calculate the heat capacity of the cup, in units of J/K. This will tell us how many Joules of heat the cup absorbs for every K (or degree C) the water heats up. We know how many Joules of heat we added with the hot water, and we can calculate how many Joules were absorbed by the cold water as it warmed up.

  • Oxide Fuel Cells with Hydrocarbon and Syngas Fuels—A Review
    Fundamentals of electro- and thermochemistry in the anode of solid- oxide fuel cells with hydrocarbon and syngas fuels—a review Jeffrey Hanna,∗a Won Yong Lee,a Yixiang Shi,b and Ahmed F. Ghoniema Received Xth XXXXXXXXXX 20XX, Accepted Xth XXXXXXXXX 20XX First published on the web Xth XXXXXXXXXX 200X DOI: 10.1039/b000000x High fuel flexibility of solid-oxide fuel cells (SOFCs) affords the possibility to use relatively cheap, safe, and readily available hydrocarbon (e.g., CH4) or coal syngas (i.e., CO-H2 mixtures) fuels. Utilization of such fuels would greatly lower fuel cost and in- crease the feasibility of SOFC commercialization, especially for near-term adoption in anticipation of the long-awaited so-called “hydrogen economy.” Current SOFC technology has shown good performance with a wide range of hydrocarbon and syngas fu- els, but there are still significant challenges for practical application. In this paper, the basic operating principles, state-of-the-art performance benchmarks, and SOFC-relevant materials are summarized. More in-depth reviews on those topics can be found in Kee and co-workers [Combust. Sci. and Tech., 2008, 180, 1207–1244 and Proc. Combust. Inst., 2005, 30, 2379–2404] and McIntosh and Gorte [Chem. Rev., 2004, 104, 4845–4865]. The focus of this review is on the fundamentals and development of detailed electro- and thermal (or simply, electrothermal) chemistry within the SOFC anode, including electrochemical oxidation mechanisms for H2, CO, CH4, and carbon, as well as the effects of carbon deposition and sulfur poisoning. The interdependence of heterogeneous chemistry, charge-transfer processes, and transport are discussed in the context of SOFC-membrane-electrode assembly (MEA) modeling.

  • Thermochemistry of the Formation of Fossil Fuels
    Fluid-Mineral Interactions: A Tribute to H. P. Eugster © The Geochemical Society, Special Publication No.2, 1990 Editors: R. J. Spencer and I-Ming Chou Thermochemistry of the formation of fossil fuels MOTOAKI SATO U.S. Geological Survey, MS 959, Reston, Virginia 22092, U.S.A. Abstract-Photosynthesis liberatesO2 from a mixture of CO2 and H20 in forming biologicalsubstances. Formation of fossil fuels is also associated with progressive depletion of oxygen from biological substances. The two processes are thus sequential in terms of deoxygenation. To evaluate thermo- chemical relations of the deoxygenation processes in a simple manner, the concept of deoxygenation free energy Gdeox and deoxygenation enthalpy Hdeox (defined as Gibbs energy and enthalpy, respectively, of reaction to release unit mole of O2 in forming a compound CxHyNzOw from CO2, H20, and N2) are computed for over 150 compounds. If compound A changes to compound B by dehydration and/or decarboxylation, and A has a higher Gdeox value than B, energy is released and the transformation can occur spontaneously; likewise heat is released if A has a higher Hdeox' The computed results indicate that energy input is required only for the initial stage of photosynthesis, and progressive deoxygenation and aromatic condensation during diagenesis should decrease free energy and release heat. Catagenesis and metagenesis are also most probably spontaneous and exothermic because both low C-number paraffinic hydrocarbons and polycondensed aromatic kerogens have the lowest Gdeox and Hdeox values among various homologous groups even at room temperature. The ultimate products of the spontaneous evolution of fossilfuelsare methane and graphite. The role of increased temperature associated with deeper burial is not to change the position of equilibrium, but simply to increase the reaction rate exponentially so that the extremely slow reactions would proceed in geologic time.

  • The Start of the Abiogenesis: Preservation of Homochirality In
    The start of the Abiogenesis: Preservation of homochirality in proteins as a necessary and sufficient condition for the establishment of the metabolism Søren Toxvaerd Department of Science and Environment, Roskilde University, Postbox 260, DK-4000 Roskilde, Denmark Abstract Biosystems contain an almost infinite amount of vital important details, which together ensure their life. There are, however, some common struc- tures and reactions in the systems: the homochirality of carbohydrates and proteins, the metabolism and the genetics. The Abiogenesis, or the origin of life, is probably not a result of a series of single events, but rather the result of a gradual process with increasing complexity of molecules and chemical reactions, and the prebiotic synthesis of molecules might not have left a trace of the establishment of structures and reactions at the beginning of the evo- lution. But alternatively, one might be able to determine some order in the formation of the chemical denominators in the Abiogenesis. Here we review experimental results and present a model of the start of the Abionenesis, where the spontaneous formation of homochirality in proteins is the precon- dition for the establishment of homochirality of carbohydrates and for the metabolism at the start of the Abiogenesis. Keywords: arXiv:1803.01560v1 [q-bio.BM] 5 Mar 2018 Abiogenesis Homochirality Metabolism 1. The preservation of homochiral structures in millions of years in a prebiotic aqueous environment. There have been many proposals to the establishment of homochirality of carbohydrates and amino acids in a prebiotic environment. It is, however, not the establishment, but rather the preservation of homochirality, which is the problem.

  • AJR Ch6 Thermochemistry.Docx Slide 1 Chapter 6
    Chapter 6: Thermochemistry (Chemical Energy) (Ch6 in Chang, Ch6 in Jespersen) Energy is defined as the capacity to do work, or transfer heat. Work (w) - force (F) applied through a distance. Force - any kind of push or pull on an object. Chemists define work as directed energy change resulting from a process. The SI unit of work is the Joule 1 J = 1 kg m2/s2 (Also the calorie 1 cal = 4.184 J (exactly); and the Nutritional calorie 1 Cal = 1000 cal = 1 kcal. A calorie is the energy needed to increase the temperature of 1 g of water by 1 °C at standard atmospheric pressure. But since this depends on the atmospheric pressure and the starting temperature, there are several different definitions of the “calorie”). AJR Ch6 Thermochemistry.docx Slide 1 There are many different types of Energy: Radiant Energy is energy that comes from the sun (heating the Earth’s surface and the atmosphere). Thermal Energy is the energy associated with the random motion of atoms and molecules. Chemical Energy is stored within the structural units of chemical substances. It is determined by the type and arrangement of the atoms of the substance. Nuclear Energy is the energy stored within the collection of protons and neutrons of an atom. Kinetic Energy is the energy of motion. Chemists usually relate this to molecular and electronic motion and movement. It depends on the mass (m), and speed (v) of an object. ퟏ ke = mv2 ퟐ Potential Energy is due to the position relative to other objects. It is “stored energy” that results from attraction or repulsion (e.g.

Subject of thermodynamics All chemical reactions are accompanied by transformation of chemical energy to other forms of energy - thermal, electrical, mechanical, etc. Thermodynamics is the branch of physical science that studies all forms of energy and their mutual transformations; therefore it is sometimes called energetics. Bioenergetics is a field of thermodynamics that deals with biosystems. Classical thermodynamics is based on propositions which are confirmed by experiment and does not use knowledge about the molecular structure of substances.The energy of reactions is studied by the branch of thermodynamics which is called thermochemistry or chemical thermodynamics. In thermochemistry two types of chemical reactions are distinguished: exothermic (are accompanied by heat release) and endothermic (are accompanied by heat absorption). There are reactions (not so numerous), which are not accompanied by heat exchange. Chemical reactions can occur at a constant pressure (for example in an open flask) - these are isobaric processes, at a constant volume (in a closed flask or an autoclave) - these are isochoric processes, or at a constant temperature - these are isothermal processes (the names are derived from the Greek words isos - identical, baros - pressure, chorus - space, thermos - heat). Thermodynamics deals with the study of properties of various thermodynamic systems and processes occurring in them.
