Question

What is the role of the metal catalysts that are used in the Haber-Bosch process, 3H₂(g) + N₂(g) ⇌ 2NH₃(g)?

Possible answers:

To drive the reaction to form more products

To drive the reaction to form more reactants.

To decrease the temperature of the reaction.

To increase the temperature of the reaction.

To achieve equilibrium faster.

Answer 1

The catalyst has no effect on the position of equilibrium that is greater amount of ammonia production. In absence of catalyst virtually no reaction takes place.On addition of catalyst the equilibrium is attained at a faster rate within shorter time. The reaction requires high temperature even in presence of catalyst. Therefore the role of catalyst is to achieve equilibrium faster.
