Q. If the equilibrium constant for $N_2(g) + O_2(g) \rightleftharpoons 2NO(g)$ is K, the equilibrium constant for $\frac{1}{2}N_2(g) + \frac{1}{2}O_2(g) \rightleftharpoons NO(g)$ will be :-
A) K
B) $K^2$
C) $K^{1/2}$
D) $\frac{1}{2}K$
Explanation
[Solution] Multiplying a reaction by 1/2 raises K to the power 1/2: $K' = K^{1/2}$. Answer (3).
