For this problem, use the "Thermodynamic Properties of Selected Substances" table in the "Reference Data" section at the back of your textbook. Suppose you have a mole of methane (CH., otherwise known as "natural gas") at 25°C and atmospheric pressure. (a) rotational, with vibrational frozen out). Further suppose we choose the reference point for the thermodynamic potentials such that we neglect the rest energies of the molecules, and express U as simply 3NRT. Calculate S, H, F, and G for the mole of methane. Suppose the methane behaves as an ideal gas with 6 degrees of freedom (3 translational + 3 If you raise the temperature of the mole of methane to 28°C (keeping the pressure constant), (b) what is the change in its Gibbs free energy? When methane is burned as fuel, the following chemical reaction takes place: CH, + 20, - 2H;0 + CO, (c) Determine the values of AG and AH for this reaction. (d) How much heat is produced in this reaction, per mole of methane?
