Question
Transcribed Image Text:21. Solid ammonium carbamate, NH4CO₂NH2, decomposes to ammonia and carbon dioxide when it sublimes:
NH4CO₂NH2 (s) = 2NH3(g) +CO2 (g)
Imagine a sample of ammonium carbamate is allowed to decompose in an evacuated sealed container at 25°C
(evacuated means no gas components at the start of the reaction). The decomposition is endothermic, and the
Kp at 25°C is 2.3 x104.
Tuming
a. What are the partial pressures of NH3 and CO₂ at equilibrium? What is the total pressure in the container
at equilibrium? Assume the mixture is ideal.
