Question

The equilibrium constants for the following are:
$N_{2} + 3 H_{2} ⇌ 2 N H_{3} K_{1}$
$N_{2} + O_{2} ⇌ 2 N O K_{2}$
$H_{2} + \frac{1}{2} O_{2} \to H_{2} O K_{3}$
The equilibrium constant (K) of the reaction:
$2 N H_{3} + \frac{5}{2} O_{2} K ⇌ 2 N O + 3 H_{2} O,$ will be

Solution

The correct option is B $K_{2} K_{3}^{3} / K_{1}$
$(I) N_{2} + 3 H_{2} ⇌ 2 N H_{3}; K_{1} = \frac{[N H_{3}]^{2}}{[N_{2}] [H_{2}]^{3}} (I I) N_{2} + O_{2} ⇌ 2 N O; K_{2} = \frac{[N O]^{2}}{[N_{2}] [O_{2}]} (I I I) H_{2} + \frac{1}{2} O_{2} ⟶ H_{2} O; K_{3} = \frac{[H_{2} O]}{[O_{2}]^{\frac{1}{2}}}$
$(I I + 3 \times I I I - I I)$ will give
$2 N H_{3} + \frac{5}{2} O_{2} K ⇌ 2 N O + 3 H_{2} O$
$∴ K = K_{2} \times K_{3}^{3} / K_{1}$
