The equilibrium constants of the following are.                                                             [NEET-2017]

\[{{N}_{2}}+3{{H}_{2}}\rightleftharpoons 2N{{H}_{3}}\,{{K}_{4}}\]

\[{{N}_{2}}+{{O}_{2}}\rightleftharpoons 2NO\,{{K}_{2}}\]

\[{{H}_{2}}+\frac{1}{2}{{O}_{2}}\xrightarrow{{}}{{H}_{2}}O\,{{K}_{3}}\]

The equilibrium constant (K) of the reaction \[2N{{H}_{3}}+\frac{5}{2}{{O}_{2}}\xrightarrow{k}2NO+3{{H}_{2}}O,\] will be

A)  \[K_{2}^{3}{{K}_{3}}/{{K}_{1}}\]    

B)       \[{{K}_{1}}K_{3}^{3}/{{K}_{2}}\]

C)  \[{{K}_{2}}K_{3}^{3}/{{K}_{1}}\]    

D)       \[{{K}_{2}}{{K}_{3}}/{{K}_{1}}\]
