  1. (D) In a closed system, decreasing the size of the container will cause the
    pressure to increase. When pressure is applied to an equilibrium involving
    gases, the reaction that lowers the pressure by decreasing the number of
    molecules will increase in rate. In this reaction, the rate of the reverse
    reaction, in which 2 molecules are decreased to 1, increases, thus reducing
    pressure while also increasing the concentration of N 2 O 4. Thus, II and III are
    true.
