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.

Select all of the correct statements about equilibrium from the choices below. At equilibrium the rates of forward and reverse reactions are equal. At equilibrium the rate of change of product concentration is zero. At equilibrium the forward rate constant equals zero. As a reaction proceeds backwards toward equilibrium the reverse rate drops. As a reaction proceeds forward toward equilibrium the reactant concentrations drop. At equilibrium no more reactants are transformed into products.
