The Reaction Shown Below Is Exothermic:2 NO₂ (G) $\rightarrow$ N₂O₄(g)At Low Pressures It Is NOT Spontaneous, but at High

The reaction shown below is exothermic:2 NO₂ (g) $\rightarrow$ N₂O₄(g) At low pressures it is NOT spontaneous, but at high pressures, significant amounts of product are formed. This is because

A) the heavier products cause greater disorder upon collisions.
B) the smaller number of product molecules leads to more disorder in the container.
C) to place the system under high pressure, the surroundings are more disordered.
D) the higher pressures make the reaction proceed more rapidly.
E) at low pressure more molecules are required to fill the same space.
