1) To calculate the standard reaction entropy at 298 K of sucrose [C12H22O11(s) + 12O2(g) 12 CO2(g) + 11H2O(l). Given the standard molar entropy ( ) at 298 K for C12H22O11(s) is 360.2 J/Kmol, O2(g) is 205.138 J/Kmol, CO2(g) is 213.74 J/Kmol, and H2O(l) is 69.91 J/Kmol.

2) Calculate the maximum non-expansion work per mole of C3H8 that may be obtained from a fuel cell in which the chemical reaction is the combustion of propane, C3H8(g) + 5O2(g) 3CO2(g) + 4H2O(l) under 1 bar and 298 K. Given the standard Gibbs energies of formation (fG ) at 298 K for C3H8(g) is -23.49 kJ/mol, O2(g) is 0 kJ/mol, CO2(g) is -394.36 kJ/mol, and H2O(l) is -237.13 kJ/mol.
