For a gas-phase reaction at 298 K298\,\text{K}, ΔG∘\Delta G^{\circ} is measured to be +13.3 kJ⋅mol−1+13.3\,\text{kJ}\cdot\text{mol}^{-1}. What is log⁡10K\log_{10}K (base-10 logarithm of the equilibrium constant) at this temperature? (R=8.314 J⋅mol−1⋅K−1R = 8.314\,\text{J}\cdot\text{mol}^{-1}\cdot\text{K}^{-1}) (a) −5.37-5.37 (b) 2.332.33 (c) −2.33-2.33 (d) 5.375.37
