According to Le Chatelier's Principle, what will happen to the equilibrium of the reaction $N_2 + 3H_2 \rightleftharpoons 2NH_3 + Heat$ if the temperature is increased?
AMore ammonia will be formed
BThe equilibrium shifts to the left (reactants)
CThe concentration of nitrogen will decrease
DThere will be no change
✓ Correct Answer: B — The equilibrium shifts to the left (reactants)
This is an exothermic reaction. Increasing temperature favors the endothermic direction (reverse), so the equilibrium shifts to the left.
