Quizplus · Accepted Answer

At equilibrium, the reaction quotient (Q) is equal to the equilibrium constant (K), meaning that there is no net direction of the reaction (neither reactants nor products are favored), and the Gibbs free energy change (ΔG) is zero. Choice A states that ΔG = 0 and Q = K, which is consistent with a reaction at equilibrium. Choices B, C, D, and E all have non-zero values for ΔG and/or Q, indicating that the reaction is not at equilibrium.
