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. If Q > K the reaction must progress backward to attain equilibrium. As a reaction progresses forward toward equilibrium K is the highest value Q attains. If Q < K the reaction must progress backwards to attain equilibrium. A reaction quotient is the same as an equilibrium constant. The further away from K the Q...
