Solution

The correct option is D $\sqrt{K}$
If the equilibrium constant for $N_{2} (g) + O_{2} (g) ⇌ 2 N O (g)$ is $K$ , the equilibrium constant for
$\frac{1}{2} N_{2} (g) + \frac{1}{2} O_{2} (g) ⇌ N O (g)$
will be $K^{'} = \sqrt{K}$
$K = \frac{[N O]^{2}}{[N_{2}] [O_{2}]}$
$K^{'} = \frac{[N O]}{\sqrt{[N_{2}] [O_{2}]}} = \sqrt{\frac{[N O]^{2}}{[N_{2}] [O_{2}]}} = \sqrt{K}$
