Problem

Consider the reaction A(g)⇌B(g)\text{A}(g) \rightleftharpoons \text{B}(g) at 298 K for which the standard free-energy change of the forward reaction is ΔG∘=+6.0 kJ mol−1\Delta G^{\circ}=+6.0\,\text{kJ}\,\text{mol}^{-1}. Evaluate the following statements. I. K<1K<1 for the forward reaction. II. For the reverse reaction B(g)⇌A(g)\text{B}(g) \rightleftharpoons \text{A}(g), ΔG∘=−6.0 kJ mol−1\Delta G^{\circ}=-6.0\,\text{kJ}\,\text{mol}^{-1}. III. At equilibrium the mixture contains substantially more B than A. Which option correctly identifies the true statements? a) I only b) I and II only c) II and III only d) I and III only
