(i) $N_{2} (g) + O_{2} (g) ⇌ 2 N O (g)$
(ii) $N O (g) ⇌ N_{2} (g) + \frac{1}{2} O_{2} (g)$

A

K_{1} = (1 / K_{2})^{2}

Solution

The correct option is C $K_{1} = (1 / K_{2})^{2}$
$N_{2} + O_{2} ⇌ 2 N O K_{1}$
$N O ⇌ \frac{1}{2} N_{2} + \frac{1}{2} O_{2} K_{2}$
The reaction is halved and reversed
$K_{2} = \sqrt{\frac{1}{K_{1}}} \Rightarrow K_{1} = \frac{1}{{K_{2}}^{2}}$
