Entropy of acetic acid
WebAug 9, 2024 · 2.4. The knowledge of the absolute entropies of substances allows us to calculate the entropy change (ΔSo) for a reaction. For example, the entropy change for the vaporization of water can be found as follows: ΔSo = So(H 2O(g)) − So(H 2O(l)) = 188.7J/K ⋅ mol − 69.9J/K ⋅ mol = 118.8J/K ⋅ mol. The entropy change for the vaporization ...
