Select all of the correct statements about reaction quotients and equilibrium constants from the choices below. A reaction quotient equals the equilibrium constant at equilibrium. In a reacting mixture K is the ratio of product to reactant concentrations. As a reaction progresses forward toward equilibrium K is the highest value Q attains. As a reaction progresses forward toward equilibrium Q rises. If Q = K the reaction is already at equilibrium. As a reaction progresses forward toward equilibrium Q drops.
