Equilibrium Ques 37
37. If the equilibrium constant for
$N_2(g)+O_2(g) \rightleftharpoons 2 NO(g)$ is $K$, the equilibrium constant for
$\frac{1}{2} N_2(g)+\frac{1}{2} O_2(g) \rightleftharpoons NO(g)$ will be:

(c) $K$
(d) $K^{2}$

Answer:
Correct Answer: 37.(a)
Solution:
- (a) $N_2(g)+O_2(g) \rightleftharpoons 2 NO(g)$
$K=\frac{[NO]^{2}}{[N_2][O_2]}$
$ \begin{aligned} & \frac{1}{2} N_2+\frac{1}{2} O_2 \rightleftharpoons NO \\ & K^{\prime}=\frac{[NO]}{[N_2]^{1 / 2}[O_2]^{1 / 2}}=K^{1 / 2} \end{aligned} $
