Problem: At 25ºC, Kp = 2.9 x 10 -3 for the reactionNH4OCONH2(s) ⇌ 2NH3(g) + CO2(g)In an experiment carried out at 25ºC, a certain amount of NH4OCONH2 is placed in an evacuated rigid container and allowed to come to equilibrium. Calculate the total pressure in the container at equilibrium.

FREE Expert Solution

We are asked to calculate the total pressure in the container at equilibrium.


Step 1. Set up ICE chart 



Step 2. Calculate x

 Kp = productsreactantsKp = (PNH3)2(PCO2)2.9× 10 -3= (2x)2(x)2.9× 10 -3=4x3x = 2.9× 10 -343

x = 0.090 atm
