Calculate ΔS°_rxn for the following reaction.The S^∘for each species is shown below the reaction. C₂H₂(g)+ 2 H₂(g)→ C₂H₆(g) S°(J/mol^∙K)200.9 130.7 229.2

Quizplus · Accepted Answer

ΔS°rxn = ΣnS°products - ΣnS°reactants ΔS°_rxn = (2 mol)(130.7 J/K) + (1 mol)(200.9 J/K) - (1 mol)(229.2 J/K) - (2 mol)(130.7 J/K) = -233.1 J/K Therefore, the answer is D.
