Question

Statement-I : Reaction quotient is defined in the same way as equilibrium constant at any stage of the reaction.\ Statement-II: If $Q$ (reaction quotient) $<K_c$ (equilibrium constant) reaction moves in direction of reactants.

(b) : For the reaction $a A+b B ightleftharpoons c C+d D$, $ Q=\frac{[C]^c[D]^d}{[A]^a[B]^b} \ $ If $Q>K_c$, reaction will proceed in the direction of reactants. \ If $Q<K_c$, reaction will move in direction of products. \If $Q=K_c$, the reaction mixture is already at equilibrium.
