Heterogeneous Catalysis -

The catalytic process in which the reactants and the catalyst are in different phases is known as heterogeneous catalysis

- wherein

E.g. 2SO_{2}(g) \underset{Pt(s)}{\rightarrow}2SO_{3(g)}

 

As we have learned in combustion we do not require any catalyst forf the combustion of coal.

 


Option 1)

Ostwald's process

 

Option 2)

Combustion of coal

Option 3)

Hydrogenatoin of vegetable oils
