For the equilibrium 2NO2(g)⇌N2O4(g)2NO_2(g) ⇌ N_2O_4(g), Kp=6.8K_p = 6.8 at 45°C. A reaction mixture has partial pressures PNO2=0.35P_{NO_2} = 0.35 atm and PN2O4=0.82P_{N_2O_4} = 0.82 atm. To predict the direction of reaction, a student calculates Qp=0.82(0.35)2=6.7Q_p = \frac{0.82}{(0.35)^2} = 6.7. What conclusion should the student draw?
