Question

Solid ammonium carbamate, $N H_{4} C O_{2} N H_{2} (s)$ , dissociates into ammonia and carbon dioxide when it evaporates as shown by
$N H_{4} C O_{2} N H_{2} (s) ⇌ 2 N H_{3} (g) + C O_{2} (g)$
At $25^{\circ} C$ , the total pressure of the gases in equilibrium with the solid is $0.116 atm$ , if $0.1 atm$ of $C O_{2}$ is introduced after equilibrium is reached then:

The final pressure of

C O_{2}

will be less than

Solution

The correct option is C The pressure of $N H_{3}$ will decrease due to addition of $C O_{2}$
$N H_{4} C O_{2} N H_{2} (s) ⇌ 2 N H_{3} (g) + C O_{2} (g)$

On addition of $C O_{2}$ the reaction moves backwards to keep $K_{p}$ constant hence the pressure of $N H_{3}$ decreases.
Also, since 0.1 atm of $C O_{2}$ is introduced after equilibrium is obtained, its pressure will be more than 0.1 atm.
