Given

{N_2}\left( g \right) + 3{H_2}\left( g \right) \rightleftharpoons 2N{H_3}\left( g \right);\,\,{K_1}

{N_2}\left( g \right) + {O_2}\left( g \right) \rightleftharpoons 2NO\left( g \right);\,\,{K_2}

{H_2}\left( g \right) + \frac{1}{2}{O_2}\left( g \right) \rightleftharpoons {H_2}O\left( g \right);\,\,{K_3}

The equilibrium constant for

2N{H_3}\left( g \right) + \frac{5}{2}{O_2}\left( g \right) \rightleftharpoons 2NO\left( g \right) + 3{H_2}O\left( g \right)

will be

View answer and explanation

Correct option: D

\frac{{{K_2}K_3^3}}{{{K_1}}}

Option D (

{{K_2}K_3^3}/{{K_1}})

is correct because it represents the equilibrium constant for the target reaction derived from manipulating the given equilibrium reactions.
