What is heterogeneous catalysis? Give an example.

Explanation

When the catalyst forms a separate phase (usually a solid phase). It is said to be heterogeneous and the catalysis is hetergenous catalyst. Example of hetergeneous. Catalyst is manufacture of `H_2SO_4` in contact process using `V_2O_5` as catalyst. Usally in a hetergenous catalyst the reactant are gases and reaction starts from the surface of the solid catalyst. this is the reason why hetergeneous catalyst is also called .surface catalysis.
