At constant temperature and pressure, which of the following statements about the relationship between the reaction quotient Q and the equilibrium constant K is CORRECT?
a) If Q>K, the forward reaction has ΔG<0 and proceeds spontaneously.
b) If Q=K, the forward reaction has ΔG∘=0 and proceeds spontaneously.
c) If Q<K, the forward reaction has ΔG<0 and proceeds spontaneously.
d) If Q<K, the forward reaction has ΔG>0 and is non-spontaneous.
