Given are the information:
(i) $2 \mathrm{H}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) ightleftharpoons 2 \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) ; \quad K_{p 1}$
(ii) $\mathrm{N}_{2}(\mathrm{~g})+3 \mathrm{H}_{2}(\mathrm{~g}) ightleftharpoons 2 \mathrm{NH}_{3}(\mathrm{~g}) \quad K_{p 2}$
(iii) $4 \mathrm{NH}_{3}(\mathrm{~g})+5 \mathrm{O}_{2}(\mathrm{~g}) ightleftharpoons 4 \mathrm{NO}(\mathrm{g})+6 \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) ; \quad K_{p 3}$
The expression of $K_{p}$ for the reaction $\mathrm{N}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) ightleftharpoons 2 \mathrm{NO}(\mathrm{g})$ is
  1. $K_{p 2}^{1 / 2} K_{p 3} / K_{p 1}^{3 / 2}$
  2. $K_{p 1} K_{p 2}^{1 / 2} / K_{p 3}^{3 / 2}$
  3. $K_{p 2} K_{p 3}^{1 / 2} / K_{p 1}^{3 / 2}$
  4. $K_{p 2} K_{p 3}^{1 / 2} / K_{p 1}^{1 / 2}$

Solution

Given equation is obtained by the manipulations Eq.(ii) $-\frac{3}{2}$ Eq. (i) $+\frac{1}{2}$ Eq. (iii)
