Calculate the Gibbs free energy change at standard conditions for the combustion of propane:C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(l) Given the standard enthalpy of formation data: ΔH°f(CO2(g)) = -393.5 kJ/mol ΔH°f(H2O(l)) = -285.8 kJ/mol ΔH°f(C3H8(g)) = -103.85 kJ/mol and the standard entropy data: S°(CO2(g)) = 213.6 J/(mol•K) S°(H2O(l)) = 69.9 J/(mol•K) S°(C3H8(g)) = 269.9 J/(mol•K)
