... The chemical reaction in this example is of environmental interest. Iron pyrite (FeS2 ) is often an impurity in coal, and so burning this fuel in a power plant produces sulfur dioxide ( SO 2 ), a major air pollutant. Our next example also involves burning a fuel and its effect on the atmosphere. ...

... P4O10 and SO2. In principle, you could calculate Hrxn from enthalpies of formation for the reactants and products of this reaction. You would require the values for P 4S3, O2 (which equals zero), P4O10, and SO2. Enthalpies of formation for the products, P4O10 and SO2, are given in Table 6.2 in the ...

Chemical thermodynamics
Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. Chemical thermodynamics involves not only laboratory measurements of various thermodynamic properties, but also the application of mathematical methods to the study of chemical questions and the spontaneity of processes.The structure of chemical thermodynamics is based on the first two laws of thermodynamics. Starting from the first and second laws of thermodynamics, four equations called the ""fundamental equations of Gibbs"" can be derived. From these four, a multitude of equations, relating the thermodynamic properties of the thermodynamic system can be derived using relatively simple mathematics. This outlines the mathematical framework of chemical thermodynamics.
