(b) NO2 is a toxic brownish-yellowish gas. At room temperature it is also in equilibrium with its colorless dimer, N2O4. The equilibrium constant of the dimerization reaction is given as Kp= 57.6. NO2 (g) ⇌ N2O4 (g) If a sample of this equilibrium mixture placed in a cylinder exerted the pressure of 0.5 bar at room temperature, what would be the partial pressure of the N2O4 in this mixture?
