Question

When elemental nitrogen gas and elemental hydrogen gas are placed in a closed system, some small amount of ammonia gas will form as the system comes to equilibrium. What could be the possible cause(s) for more nitrogen and hydrogen forming?

Pressure of the system is decreased

Explanation / Answer

This goes by the Le-chatelier's principle

N2 + 3H2 ----- > 2NH3

So, if the pressure is decreased or volume is increased, the reaction moves in the direction of greater number of moles.

Hence, option A is the answer.

Pressure of the system is decreased
