Which is true for a chemical reaction at equilibrium?

Question

Quizplus · Accepted Answer

At equilibrium, the rates of the forward and reverse reactions are equal, which means there are no observable changes at the macroscopic level. However, at the microscopic level, the reactant molecules are still constantly forming products and vice versa. Therefore, the correct option is A. Option B is incorrect because the reaction has not stopped, it is just in a state of dynamic equilibrium. Option C is incorrect because the reaction is occurring at equilbrium, which means the forward and reverse reactions are proceeding at the same rate. Option D is incorrect because the molecules are still moving at equilibrium, they are just not changing in concentration.
