Which of the following describes any reaction that has reached chemical equilibrium?

Question

Quizplus · Accepted Answer

At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. This means that the concentrations of the reactants and products may not necessarily be equal, and the reaction may not necessarily have gone to completion (options C and D). Option A is also not necessarily true, as the concentrations of reactants and products may be different but still result in the same rate of the forward and reverse reactions. Option E is not a complete definition of equilibrium, as equilibrium is characterized not just by the cessation of reactions, but also by the balance between the forward and reverse reactions.
