The Haber process produces ammonia as shown in the equilibrium equation below.

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

The Haber process is occurring in a reaction chamber. When equilibrium is reached in the reaction chamber, the volume of the chamber is decreased. This increases the pressure inside the reaction chamber. What will happen as a result of this increase in pressure?

A.
The reverse reaction will happen more slowly than the forward reaction.
B.
The forward reaction will happen more slowly than the reverse reaction.
C.
Only the forward reaction will happen.
D.
Only the reverse reaction will happen.
