The reaction N2O4(g) → 2NO2(g) has the equilibrium constant KP=0.450 at 349 K. If the partial pressures of N2O4 and NO2 in a certain mixture are 320. torr and 12 torr, respectively, which of the following statements is true? A. N2O4 and NO2 are in equilibrium. B. N2O4 and NO2 are not in equilibrium, because PNO2 < PN2O4. c. C. More N2O4 must be formed to reach equilibrium. D. N2O4 and NO2 are not in equilibrium, but additional information is needed to predict how the two gases will behave so they eventually reach equilibrium. E. Certain amount of N2O4 must decompose to reach equilibrium.
