Solution

For the calculation of equilibrium constant, only gaseous reactants are considered.
$N H_{2} C O O N H_{4} (s) ⇌ 2 N H_{3} (g) + C O_{2} (g)$
$t = 0, C 00$
$t = t_{e q m} C - x 2 x x$

Given, $p_{C O_{2}} = 1 a t m$
$∴$ $p_{C O_{2}} = \frac{x}{3 x} P_{t o t a l} = \frac{P_{Total}}{3} = 1 atm$
Again, $P_{N H_{3}} = \frac{2 x}{3 x} P_{t o t a l} = \frac{2 P_{Total}}{3} = 2 atm$
$∴$ $K_{p} = P_{N H_{3}}^{2} . P_{C O_{2}} = 4 {atm}^{3}$
