According to Le Chatelier's principle, if the concentration of one of the reactants or products in a system at equilibrium is changed, the equilibrium will shift in a direction that counteracts that change.
In this case, if more \( N_2 \) (nitrogen) is added to the equilibrium reaction:
\[ N_2 + 3H_2 \rightleftharpoons 2NH_3 \]
the increase in \( N_2 \) concentration will cause the equilibrium to shift to the right (towards the production of more \( NH_3 \)) in order to reduce the concentration of \( N_2 \).
Therefore, the correct answer is:
**B) Equilibrium will shift to the product and produce more \( NH_3 \).**
In this case, if more \( N_2 \) (nitrogen) is added to the equilibrium reaction:
\[ N_2 + 3H_2 \rightleftharpoons 2NH_3 \]
the increase in \( N_2 \) concentration will cause the equilibrium to shift to the right (towards the production of more \( NH_3 \)) in order to reduce the concentration of \( N_2 \).
Therefore, the correct answer is:
**B) Equilibrium will shift to the product and produce more \( NH_3 \).**
