It is because of inability of $n{s}^2$ electrons of the valence shell to participate in bonding that:

Mechanism of a hypothetical reaction $X_2+Y_2\to 2XY$ is given below:(i) $X_2\to X+X$ (fast)(ii) $X+Y_2\rightleftharpoons XY+Y$ (slow)(iii) $X+Y\to XY$ (fast)The overall order of the reaction will be:

The equilibrium constants of the following are:${\text{N}}_2+3{\text{H}}_2\rightleftharpoons 2{\text{NH}}_3(K_1)$${\text{N}}_2+{\text{O}}_2\rightleftharpoons 2\text{NO}(K_2)$${\text{H}}_2+\frac{1}{2}{\text{O}}_2\to {\text{H}}_2\text{O}(K_3)$ The equilibrium constant ($K$) of the reaction:$2{\text{NH}}_3+\frac{5}{2}{\text{O}}_2\rightleftharpoons 2\text{NO}+3{\text{H}}_2\text{O}$ will be:
