Determine $\Delta$S° for the reaction SO₃(g)+ H₂O(l) $\rarr$ H₂SO₄(l).

Question

Quizplus · Accepted Answer

The reaction involves a decrease in entropy as gases and liquids are converted to a solid. The equation F1F1F1S1F1F1F10S° = ∆S°products - ∆S°reactants can be used to calculate the standard entropy change. We can calculate the value of ∆S°reactants + ∆S°H₂ using the standard molar entropies, which yields a value of -169.2 J/K·mol. The negative sign indicates a decrease in entropy, which is expected for the conversion of gases and liquids to a solid. Therefore, the answer is (C).
