What stress will shift the following equilibrium system to the left? n2(g) + 3h2(g) ⇌ 2nh3(g) adding more n2(g) adding more nh3(g) increasing the pressure of the system reducing the volume of the container

Option (b) is the correct answer.

Explanation:

According to Le Chatelier's principle, any disturbance in an equilibrium reaction will shift the equilibrium in the opposite direction of the change.

For example,

So, when we increase the concentration of ammonia in this reaction then equilibrium gets disturbed and it will shift on the left side because on the left hand side concentration of ammonia is decreasing.

Thus, we can conclude that adding more will shift the given equilibrium system to the left.
