Essential Chemistry for IGCSE - Chemical Reactions (Section 4 - No. 4)
Consider the Haber process: N₂(g) + 3H₂(g) ⇌ 2NH₃(g). What is the effect of decreasing the temperature on the equilibrium?
The equilibrium shifts to the left.
The equilibrium shifts to the right.
The equilibrium remains unchanged.
The reaction rate slows down.
Explanation
The Haber process is exothermic (ΔH < 0), so decreasing temperature favors the forward reaction.
