    If \[{{N}_{2}}+3{{H}_{2}}2N{{H}_{3}}-K\] \[2N{{H}_{2}}+6{{H}_{2}}4N{{H}_{3}}-{K}'\] Then K' will be:

    A)  \[{{K}^{2}}\]                                     

    B)  \[\sqrt{K}\]

    C)  \[\frac{1}{\sqrt{K}}\]                    

    D)  \[\frac{1}{{{K}^{2}}}\]

    Correct Answer: A

    Solution :

                     \[{{N}_{2}}+3{{H}_{2}}2N{{H}_{3}}\] \[K=\frac{{{[N{{H}_{3}}]}^{2}}}{[{{N}_{2}}]{{[{{H}_{2}}]}^{3}}}\]                  ...(i) \[2{{N}_{2}}+6{{H}_{2}}4N{{H}_{3}}\]                 \[K'=\frac{{{[N{{H}_{3}}]}^{4}}}{{{[{{N}_{2}}]}^{2}}{{[{{H}_{2}}]}^{6}}}\] ?. (ii) From Eqs. (i) and (ii) \[K'={{K}^{2}}\]
