At equilibrium, ________. a. all chemical reactions have ceased b. the rates of the forward and reverse reactions are equal c. the rate constants of the forward and reverse reactions are equal d. the value of the equilibrium constant is 1 e. the limiting reagent has been consumed

Respuesta :

Answer: b. the rates of the forward and reverse reactions are equal

Explanation:

At equilibrium, the rates of the forward and reverse reactions are equal. Option b.  the rates of the forward and reverse reactions are equal

What happens at equilibrium?

The equilibrium state is one in which there is no net change in the concentrations of reactants and products. Nothing could be further from the truth; at equilibrium, the forward and reverse reactions continue, but at identical rates, thereby leaving the net concentrations of reactants and products undisturbed. If the reactants and products are equal in energy, at equilibrium, they will have the same concentration.

Thus, option b is correct.
