Which of the following statements is/are CORRECT? For a chemical system at equilibrium, the forward and reverse rates of reaction are equal. For a chemical system at equilibrium, the concentrations of products divided by the concentrations of reactants equals one. For a chemical system, if the reaction quotient (Q) is less than K, reactant must be converted to products to reach equilibrium.

At equilibrium the total concentration of products equals the total concentration of reactants, that is, [products] = [reactants]. B. Equilibrium is the result of the cessation of all chemical change. C. There is only one set of equilibrium concentrations that equals the Kc value. D. At equilibrium, the rate constant of the forward reaction is equal to the rate constant for the reverse reaction. E. At...
