For equilibrium N2(g)+3H2(g)2NH3(g),K1=([NH3]2/[N2][H2]3) ..... (i) N2(g)+O2(g)leftharpoons 2NO(g),K2=([NO]2/[N2] [O2]) .....(ii) H2(g)+(1/2)O2(g)leftharpoons H2O(g),K3=([H2O]/[H2] [O2]1/2).....(iii) For reaction, 2NH3(g)+(5/2)O2(g)leftharpoons 2NO(g)+3H2O(g) K=([NO]2× [H2O]3/[NH3]2 [O2]5/2)....(iv) From equations number (i), (ii) and (iii) K=(K2× K33/K1)

Q. The following equilibria are given :
$N_{2} + 3 H_{2} ⇌ 2 N H_{3} K_{1}$
$N 2 + O 2 ⇌ 2 NO K_{2}$
$H_{2} + \frac{1}{2} O_{2} ⇌ H_{2} O K_{3}$
The equilibrium constant of the reaction
$2 N H_{3} + \frac{5}{2} O_{2} ⇌ 2 NO + 3 H_{2} O$ in terms of $K_{1}, K_{2}$ and $K_{3}$ is

$K_{1} K_{1} K_{3}$

$\frac{K _{1} K _{2}}{K _{3}}$

$\frac{K _{1} K _{3}^{2}}{K _{2}}$

$\frac{K _{2} K _{3}^{3}}{K _{1}}$
