Select all of the correct statements about equilibrium from the choices below. At equilibrium the rates of forward and reverse reactions are equal. As a reaction proceeds backwards toward equilibrium the reactant concentrations rise. As a reaction proceeds backwards toward equilibrium the reverse rate drops. As a reaction proceeds forward toward equilibrium the product concentrations rise. At equilibrium concentrations of reactants and products stay constant. At equilibrium there are always equal amounts of reactants and products.

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.
