Using enthalpies of formation (Appendix C), calculate Ho for the following reaction at 25oC. Also calculate So

Question:

Using enthalpies of formation (Appendix C), calculate ∆Ho for the following reaction at 25oC. Also calculate ∆So for this reaction from standard entropies at 25oC. Use these values to calculate ∆Go for the reaction at this temperature.
C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)
