John Schreifels @GMU: What is the total entropy change at 25oC for the reaction below, if the standard entropies of reactants and products are So (C(gr)) = 5.74 J/mol*K, So (H2(g)) = 130.68 J/mol*K, and So (C2H6(g)) = 229.6000 J/mol*K and the heat of formation of C2H6(g)) is -84.6800 kJ/mol.2C(gr) + 3H2(g) → C2H6(g)
