Part a
The balanced reaction
CO(g) + 2H2(g) = CH3OH(l)
Entropy change for the reaction = sum of Entropy of formation of products - sum of Entropy of formation of reactants
ΔS°rxn = Sf(CH3OH) - Sf(CO) - 2*Sf(H2)
= 126.8 - 197.67 - 2*130.68
= - 332.23 J/K
Part b
The balanced reaction
N2(g) + 3H2(g) = 2NH3(g)
Entropy change for the reaction = sum of Entropy of formation of products - sum of Entropy of formation of reactants
ΔS°rxn = 2*Sf(NH3) - Sf(N2) - 3*Sf(H2)
= 2*192.45 - 191.61 - 3*130.68
= - 198.75 J/K
