Given that S° = 131 J/Kmol for H₂(g), estimate the value of ΔS° for the reaction

Question

Quizplus · Accepted Answer

Since the given reaction only involves one molecule, we can directly use the standard entropy of formation of the gas phase species H₂(g). The change in entropy for the reaction is given by the sum of the standard entropies of the products minus the sum of the standard entropies of the reactants: ΔS° = S°(11eaaf91_9e18_1aef_892c_e1204d2a77d5_TB6422_00) - S°(H₂(g)) ΔS° = 0 - 131 J/Kmol ΔS° = -131 J/Kmol Therefore, the best choice is C, because the change in entropy of the reaction is negative and equal to -131 J/K.
