Which of the following is true for a chemical reaction at equilibrium regarding the concentration of products?

Question

Quizplus · Accepted Answer

At equilibrium, the forward and reverse rates of the reaction are equal. This means that the concentrations of the products and reactants will no longer change as long as the conditions of the system remain constant. Therefore, option D is correct. Options A and B are incorrect because they imply that the reactants are completely gone, which is not necessarily the case at equilibrium. Option C is incorrect because the equilibrium constant (Kc) can vary with each reaction. Option E is incorrect because the concentrations of products and reactants remain constant at equilibrium.
