Question

The Haber process is typically carried out at a temperature of approximately 500∘C. What would happen to the rate of the forward reaction if the temperature were lowered to 100∘C? The reaction rate would _____

Answer 1

The reaction rate would decrease

Step-by-step explanation:

• The Haber process equation is given by;

N₂(g) + 3H₂(g)⇆ 2NH₃(g)

• The reaction is carried out at a temperature of 500°C which means the reaction is endothermic.
• Therefore, lowering the temperature to 100°C will decrease the rate of the forward reaction. Thus, the amount of ammonia gas formed would decrease.
• However, since the reverse reaction is exothermic, lowering the temperature would increase the rate of the reverse reaction.
