Which of the following statements is correct for a reaction at equilibrium?

A. All reactions cease to occur
B. The reaction has gone to completion
C. The rates of the forward and backward reactions are equal
D. The amount of product equals the amount of reactants

Correct Answer:

Option C – The rates of the forward and backward reactions are equal

Explanation

In a chemical reaction, chemical equilibrium is the state in which the forward reaction rate and the reverse reaction rate are equal. The result of this equilibrium is that the concentrations of the reactants and the products do not change.
