Consider the given equilibrium constants:
\(\mathrm{{N}_2+3 {H}_2 ~\rightleftharpoons 2 {NH}_3 ~~~~~~~{K}_1 \\ {N}_2+{O}_2 ~~~\rightleftharpoons 2 {NO} ~~~~~~~~{K}_2 \\ {H}_2+\frac{1}{2} {O}_2 \rightleftharpoons {H}_2 {O} ~~~~~~~~{K}_3}\)
The equilibrium constant (K) of the following reaction will be:
\(2 \mathrm{NH}_3+\frac{5}{2} \mathrm{O}_2 \stackrel{\mathrm{~K}}{\rightleftharpoons} 2 \mathrm{NO}+3 \mathrm{H}_2 \mathrm{O}\)
