When is a reversible reaction in a closed system at equilibrium?
gpt
A reversible reaction in a closed system is at equilibrium when the concentrations of the reactants and the products are no longer changing, and the rate of the forward reaction is equal to the rate of the backward reaction.
Explanation: This is a state of dynamic equilibrium, where the reaction rates are equal, and there is no net change in the concentrations of reactants and products.
