What is heterogeneous catalysis? Give an example?

1.	What is heterogeneous catalysis? Give an example?
Answer» A catalytic process in which reactants and catalyst are in different phases are known as heterogenous catalysis. E.g: 1. N₂(g) + 3H₂(g) \(\overset{Fe(s)}{\longrightarrow}\) 2NH₃ Here the reactants are gases, catalyst iron is a solid 2. Vegetable oil(l) + H₂(g) \(\overset{Ni(s)}{\longrightarrow}\) Vanaspathi ghee Here reactants and catalyst are in different phases.

Answer»

A catalytic process in which reactants and catalyst are in different phases are known as heterogenous catalysis.

E.g:

1. N₂(g) + 3H₂(g) \(\overset{Fe(s)}{\longrightarrow}\) 2NH₃

Here the reactants are gases, catalyst iron is a solid

2. Vegetable oil(l) + H₂(g) \(\overset{Ni(s)}{\longrightarrow}\) Vanaspathi ghee

Here reactants and catalyst are in different phases.
