Answer #1

Correct Answer:    A. K > 1

Gibbs free energy ΔG0rxn < 0 means that reaction is spontaneous to the right side of the given reaction (product), hence K will be larger than zero. K = [products] / [reactants] > 1 for spontaneous reactions that means ΔG0rxn < 0

Gibbs free energy ΔG0rxn = 0 means reaction is in equilibrium state, K = 0

Gibbs free energy ΔG0rxn > 0, means reaction is non-spontaneous. K < 1

All above are by definitions only.
