Above what temperature does the following reaction become nonspontaneous? 2H₂S(g) + 3O₂(g) → 2SO₂(g) + 2H₂O(g) Δ_rH = -1036 kJ; Δ_rS = -153.2 J K^-1 mol^-1

Question

Quizplus · Accepted Answer

The reaction becomes nonspontaneous when ΔG > 0. ΔG = ΔH - TΔS. Substituting the given values, we get:ΔG = -1036 kJ - T(-153.2 J K^-1 mol^-1)ΔG = -1036 kJ + 153.2 T J mol^-1Setting ΔG = 0 and solving for T, we get:0 = -1036 kJ + 153.2 T J mol^-1T = 6.762 × 10³ K
