Problem

At 298 K298\,\text{K} three reactions have the following standard free-energy changes: ΔG1∘=−25 kJ mol−1\Delta G^{\circ}_1=-25\,\text{kJ mol}^{-1} ΔG2∘=+15 kJ mol−1\Delta G^{\circ}_2=+15\,\text{kJ mol}^{-1} ΔG3∘=−10 kJ mol−1\Delta G^{\circ}_3=-10\,\text{kJ mol}^{-1} Which ranking correctly orders the equilibrium constants K1, K2, K3K_1,\,K_2,\,K_3 from largest to smallest? a) K1>K2>K3K_1 > K_2 > K_3 b) K2>K3>K1K_2 > K_3 > K_1 c) K1>K3>K2K_1 > K_3 > K_2 d) K3>K1>K2K_3 > K_1 > K_2
