Answer:
The reaction will proceed to wards left to regain the equilibrium.
Step-by-step explanation:
Equilibrium:
This is the state of reaction in which the rate of forward reaction and reverse reaction are same.
There are three factors that effect the equilibrium condition.
The change in concentration
The change in volume
The change in temperature
In given equilibrium reaction,
3H₂ + N₂ ⇄ 2NH₃
when amount of N₂ is decreased it means more amount of product is on right side and equilibrium is disturb. Thus equilibrium is shifted toward the left produces more N₂ and regain the equilibrium.
