Question

20 Which statement describes a reversible reaction at equilibrium?(1) The activation energy of the forward reaction must equal the activation energy of the reverse reaction.

(2) The rate of the forward reaction must equal the rate of the reverse reaction.
(3) The concentration of the reactants must equal the concentration of the products.
(4) The potential energy of the reactants must equal the potential energy of the products.

Answer 1

When a reaction has reached Equilibrium, the rate of the forward reaction is equal to that of the backward reaction.
