Solution: At a given temperature a system containing O2(g) and some oxides of nitrogen can be described by the following reactions:2NO(g) + O2(g) ⇌ 2NO2(g); Kp = 1042NO2(g) ⇌ N2O4(g); Kp = 0.10A pressure of 1 a

Problem

At a given temperature a system containing O2(g) and some oxides of nitrogen can be described by the following reactions:
2NO(g) + O2(g) ⇌ 2NO2(g); Kp = 104
2NO2(g) ⇌ N2O4(g); Kp = 0.10

A pressure of 1 atm of N2O4(g) is placed in a container at this temperature. Predict which, if any component (other than N2O4) will be present at a pressure greater than 0.2 atm at equilibrium.
