The Haber-Bosch Process, used to produce NH3, is governed by the following equilibrium, which has an equilibrium constant of K=9.6 at 573K:

N2(g) + 3H2(g) 2NH3(g)

The concentrations of the gases at a given point in time are:
[NH3] = 25 moles/l
[N2] = 10 moles/l
[H2] = 5 moles/l

Which of the following statements are TRUE, with respect to these conditions?

   a.    The expression for K is [NH3]2/[N2][H2]3 
   b.    The value of Q is less than K, and the reaction tends to the left to achieve equilibrium. 
   c.    Catalysts can enhance the rate at which equilibrium is achieved, but do not affect the position of the equilibrium. 
   d.    Ammonia is a non-polar molecule. This property allows it to be condensed as a liquid from the Haber-Bosch process at moderate temperatures, while the feedstock gases are returned to the reaction chamber without condensing. 
   e.    Extensive fertilization results in a shift in the the coupled equilibria of the Nitrogen Biogeochemical Cycle, driving into run off rivers, lakes, and oceans. This is a major factor behind the plume of algae growth, in the Gulf of Mexico.
