Select ALL of the correct statements about reaction quotients and equilibrium constants from the choices below. A) A reaction quotient equals the equilibrium constant at equilibrium. B) In a reacting mixture K is the ratio of product to reactant concentrations. C) A reaction quotient is the same as an equilibrium constant. D) The richer a reaction mixture is in product the higher its Q value is. E) As a reaction progresses forward toward equilibrium K is the highest value Q attains. F) As a reaction approaches equilibrium its Q value rises and its K value falls until they are equal.
