29. Which of the following statements regarding the reaction quotient (Q) and equilibrium constant (K) are correct?
(A) K is never smaller than Q.
(B) For a reversible reaction in a closed system, Q gradually approaches K as equilibrium is established.
(C) If Q > 1, the reaction always proceeds in the reverse direction.
(D) If K > Q, the reaction proceeds in the forward direction to reach equilibrium.
(E) At constant temperature, Q may change with time while K remains constant.
