Select the correct statements.

A

The value of `Q_(C)` for a given reaction is constant

B

A change in the physical state of gaseous product shows a change in the value of equilibrium constant of that reaction

C

The value of ratio of `(Q_(c))/(K_(c))` can be used to predict the direction in which a system will proceed spontaneously towards equilibrium

D

The rate constans for forward and backward reaction for a reversible reaction always increases with temperature but their ratio `(i.e. (k_(f))/(k_(b)) )` may increase or decrease with temperature.
