1. The problem statement, all variables and given/known data At 258°C, Kp = 2.9 x 10^-3 atm3 for the following reaction. NH4OCONH2(s) <--> 2 NH3(g) + CO2(g) In an experiment carried out at 258°C, 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. 2. Relevant equations I think its [NH4OCONH2]/[NH3]^2[CO2]=2.9 x 10^-3 3. The attempt at a solution I tried squaring it and also taking the square root of it but neither of it was right. I also tried the reciprocal.
