For reaction, N2(g)+3H2(g)leftharpoons 2NH3(g) Q (Quotient) = ([NH3]2/[N2] [H2]3),Δ n=2-4=-2 At equilibrium Q is equal to KC but for the progress of reaction towards right side Q > KC where KC is the equilibrium constant.

Q. The reaction quotient $(Q)$ for the reaction:
$N_{2} (g) + 3 H_{2} (g) ⇌ 2 N H_{3} (g)$
is given by $Q = \frac{[ N H _{3} ] ^{2}}{[ N _{2} ] [ H _{2} ] ^{3}} .$ The reaction will proceed from right to left if :

$Q = K_{C}$

$Q < K_{C}$

$Q > K_{C}$

$Q = 0$

For reaction, $N_{2} (g) + 3 H_{2} (g) ⇌ 2 N H_{3} (g)$

$Q$ (Quotient) = $\frac{[ N H _{3} ] ^{2}}{[ N _{2} ] [ H _{2} ] ^{3}}, Δ n = 2 - 4 = - 2$

At equilibrium $Q$ is equal to $K_{C}$ but for the progress of reaction towards right side $Q > K_{C}$ where $K_{C}$ is the equilibrium constant.
