Question

The following equilibrium constants are given
$N_{2} + 3H_{2} \rightleftharpoons 2NH_{3}; K_{1}$
$N_{2} + O_{2} \rightleftharpoons 2NO ;K_{2}$
$H_{2} + \frac{1}{2}O_{2} \rightleftharpoons H_{2}O;k_{3}$
The equilibrium constant of the reaction
$2NH_{3} + \frac{5}{2}O_{2} \rightleftharpoons 2NO + 3H_{2}O$ in terms of $K_{1},K_{2}$ an $K_{3}$ is

• A. $K=\frac{K_{2}\times K^{2}_{3}}{K_{1}}$
• B. $K=\frac{K^{2}_{2}\times K_{3}}{K_{1}}$
• C. $K=\frac{K_{1}\times K_{2}}{K_{3}}$
• D. $K=\frac{K_{2}\times K^{3}_{3}}{K_{1}}$
