For a certain reaction at 298K, the standard free-energy change is ΔG∘=+1.2kJ mol−1. Which statement best describes the composition of the equilibrium mixture under these conditions?
a) K≈1, so the equilibrium mixture will contain roughly equal amounts of reactants and products.
b) Because ΔG∘>0, essentially no reaction will occur and the system will remain entirely as reactants.
c) Since K≈0.6<1, the equilibrium mixture will contain more reactants than products, but appreciable amounts of both.
d) The positive ΔG∘ means K>1, so the mixture will consist mainly of products.
