Question

what is homogeneous and heterogeneous catalysis and example for each​

Answer 1

Answer:

Homogeneous catalysis: catalysis in which the reactants and catalyst are in same phase.I.e same physical state.

Example: 2SO2(g)+O2(g) →NO(gas)

2SO3(g)

Heterogeneous catalysis: catalysis in which the reactants and catalyst are in phases .Ie different physical states

Example: 2SO(g)+O(g)→Pt(s)2SO3(g)

Answer 2

Answer:

Homogeneous catalysis : it is a kind of catalysis in which the catalyst is present in the same phase as reactant .

for example :  

synthesis of Sulphur trioxide from Sulphur dioxide and oxygen in the presence of nitric oxide as catalyst

Heterogeneous catalysis : is catalysis that involves the catalyst in the different phase from that of reactant.

for example :

in  the process of manufacturing  ammonia , iron along with traces of K2O and Al2O3 is used as a catalyst that is in solid phase while reactants are in gaseous phase
