Question

What stress will shift the following equilibrium system to the left?

Answer 1

Answer:adding more NH3

Explanation: according to Le-chatelier principal the equilibrium shift from high concentration to lower concentration in a reversible reaction so, when we add more NH3 the concentration of product increases so that the equilibrium shift towards left.

Answer 2

Answer: 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, $N_{2}(g) + 3H_{2}(g) \rightleftharpoons 2NH_{3}(g)$

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 $NH_{3}(g)$ will shift the given equilibrium system to the left.
