Question

substance               delta Hf kj/mol                             S (J/mol'K)

CH3OH (l)                  -238.7                                       126.8

O2                                 0                                             205.07

CO2 (g)                      -393.5                                        213.8

H2O (g)                        -241.83                                    188.84

2CH3OH(g)+3O2(g)----2CO2(g)+4H2O(g)

Calculate the delta S degrees of the reaction. I need step by step directions on how to get answer.

Explanation / Answer

deta S = S of Products - S of reactants

delta S = (2*213.8)+(4*188.84)-(3*205.07)-(2*126.8) = 314.15 J/K

This is the required delta S for the given reaction.
