When a reaction is at equilibrium,

Question

Quizplus · Accepted Answer

At equilibrium, the forward and reverse reactions occur at the same rate, meaning that the conversion of reactants to products and products to reactants is balanced. Therefore, there is no net change in the concentrations of reactants and products, but the reaction is still reversible. Choice A is incorrect because the energy content of the products and reactants may not be the same. Choice B is incorrect because some reactants may continue to be converted to products and vice versa, but at an equal rate. Choice C is incorrect because there is still a reaction occurring, but it is at a balanced rate. Choice E is incorrect because the reaction is still reversible at equilibrium.
