Problem

For the reaction A ⇌ B, ΔH° = 90.0 kJ mol⁻¹ and ΔS° = 200 J mol⁻¹ K⁻¹. Above what minimum temperature will the equilibrium constant K exceed 100? (R = 8.314 J mol⁻¹ K⁻¹; ln 100 ≈ 4.605) a) ≈450 K\approx 450\,\text{K} b) ≈600 K\approx 600\,\text{K} c) ≈380 K\approx 380\,\text{K} d) ≈500 K\approx 500\,\text{K}
