Answer:

Adding more NH3(g)

Explanation:

when you add something the equilibrium shift away. So by adding to the product side it will shift left towards the reactants.

The two cases where equilibrium for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g) shifts to te left are;

  • More NH3 is added to the system
  • The pressure is decreased

What is  equilibrium?

Equilibrium is said to have been attained in a reversible reaction when the rate of forward reaction is the same as the rate of reverse reaction. We know that when equilibrium is distorted, the system readjusts itself so as as to annull the disturbance.

There are two cases in which the equilibrium may shift to the left and they are;

  • More NH3 is added to the system
  • The pressure is decreased
