Question

Solid ammonium carbamate, NH4CO2NH2(s), dissociates into ammonia and carbon dioxide when it evaporates as shown by
NH4CO2NH2(s)2NH3(g)+CO2(g)
At 25C, the total pressure of the gases in equilibrium with the solid is 0.116 atm, if 0.1 atm of CO2 is introduced after equilibrium is reached then:


A
The final pressure of CO2 will be less than 0.1 atm
loader
B
The final pressure of CO2 will be more than 0.1 atm
loader
C
The pressure of NH3 will decrease due to addition of CO2
loader
D
The pressure of NH3 will increase due to addition of CO2
loader

Solution

The correct options are
B The final pressure of CO2 will be more than 0.1 atm
C The pressure of NH3 will decrease due to addition of CO2
NH4CO2NH2(s)2NH3(g)+CO2(g)

On addition of CO2 the reaction moves backwards to keep Kp constant hence the pressure of  NH3 decreases.
Also, since 0.1 atm of CO2​ is introduced after equilibrium is obtained, its pressure will be more than 0.1 atm.
