The equilibrium will shift to the left.
The concentration of N will decrease. 2
The equilibrium will shift to the right.
The concentration of H will decrease.

Answer 1

The reaction provided is exothermic (it releases energy). According to Le Chatelier's principle, if the temperature of an exothermic reaction system increases, the equilibrium will shift to favor the endothermic direction, which is the formation of reactants.

In this case, since the reaction is: \[ N (g) + 3H (g) ⇄ 2NH (g) + \text{energy} \]

An increase in temperature will cause the equilibrium to shift to the left (toward the reactants) to absorb the added energy.

Therefore, the correct response is: The equilibrium will shift to the left.
