    In 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)  \[\frac{1}{2}K\]

    Correct Answer: C

    Solution :

     \[{{N}_{2}}(g)+{{O}_{2}}(g)\rightleftharpoons 2NO(g);K\] \[\frac{1}{2}{{N}_{2}}(g)+\frac{1}{2}{{O}_{2}}(g)\rightleftharpoons NO(g);K'\] When a reaction is multiplied by \[{}^{1}/{}_{2},\]then \[{{K}^{'}}={{(K)}^{1/2}}.\]
