Question

Quizplus · Accepted Answer

At equilibrium, the reaction has reached a state in which the rate of the forward reaction is equal to the rate of the reverse reaction. In an irreversible reaction, the reverse reaction cannot occur to any significant extent. Therefore, the only way to reach equilibrium is for almost all of the reactants to have been converted to products.
