Given the equation for a system at equilibrium:

zlopas [31]

Answer: 1. $NH_3$ increases.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given equation:

$N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)+energy$

If the concentration of $N_2$ is increased , according to the Le-Chatlier's principle, the reaction has to shift to right or forward direction. In order to do that the concentration of products has to increase.
