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

The correct statement for a reaction at equilibrium is that the rates of the forward and backward reactions are equal. This means that the reaction is still occurring, but at an equal rate in both the forward and backward directions. Equilibrium is a dynamic state in which the forward and backward reactions are still occurring, but at the same rate. This means that the concentrations of the reactants and products remain constant over time. At equilibrium, the reaction has not gone to completion and the amount of product may not necessarily equal the amount of reactants. It's important to note that equilibrium is a state of balance and not necessarily a state of rest. The reaction is still occurring, but the concentrations of the reactants and products remain constant because the rates of the forward and backward reactions are equal.
