Determining Equilibrium Pressures From Kp 007
Channel: Professor Heath's Chemistry Channel
Date: 2013-10-03

At 1000 K, a sample of pure NO2 gas decomposes by the following reaction:

2NO2 (g) ⇌ 2NO (g) + O2 (g)

The equilibrium constant Kp is 158. Analysis shows that the partial pressure of O2 is 0.25 atm at equilibrium. Calculate the pressure of NO and NO2 in the mixture.
