Consider the hypothetical reaction A + 2 B AB 2 at equilibrium.Which is true?

At equilibrium, the forward and reverse reaction rates are equal. Therefore, the forward reaction rate is equal to the reverse reaction rate. Options A, B, and C are not necessarily true at equilibrium. Option E is incorrect because the equilibrium reaction rate is zero, as there is no net change in concentration.
