Calculate ΔS°_rxn for the following reaction.The S° for each species is shown below the reaction. N₂H₄(l)+ H₂(g)→ 2 NH₃(g) S° (J/mol∙K)121.2 130.7 192.8

Quizplus · Accepted Answer

The correct answer is A because the change in entropy is calculated by subtracting the sum of the entropies of the reactants from the sum of the entropies of the products. In this case, the change in entropy is 192.8 J/mol∙K + 130.7 J/mol∙K - 121.2 J/mol∙K = 202.3 J/mol∙K.
