Answer : The equilibrium will shift in the left direction.
Explanation :
Le-Chatelier's principle : This principle states that if any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
The given reaction is:
[tex]2NH_3(g)\rightleftharpoons N_2(g)+3H_2(g)[/tex]
As per question, when we are adding [tex]N_2[/tex] then the concentration of [tex]N_2[/tex] is increased on product side then the equilibrium will shift in the direction where decrease of concentration of [tex]N_2[/tex] takes place. Therefore, the equilibrium will shift in the left direction.
Thus, the equilibrium will shift in the left direction.
