Which of the following statements is true?

Question

Quizplus · Accepted Answer

At equilibrium, the rates of the forward and reverse reactions are equal, so there is no net change in the concentrations of reactants and products.

B is incorrect because a catalyst does not change the position of equilibrium but rather speeds up both the forward and reverse reactions.

C is incorrect because the concentrations of reactants and products are not necessarily equal at equilibrium, but their ratio (known as the equilibrium constant) is constant.

D is incorrect because adding heat to an endothermic reaction generally shifts the equilibrium towards the products in order to absorb the extra heat.
