Which factors must be equal in a reversible chemical reaction at equilibrium?
(1) the activation energies of the forward and reverse reactions
(2) the rates of the forward and reverse reactions
(3) the concentrations of the reactants and products
(4) the potential energies of the reactants and products



Answer :

(2) the rates of the forward and reverse reactions
(2) the rates of the forward and reverse reactions
the rest of the choices can be unequal but the rates must be equal to each other
