Question

Difference between Homogenous catalyst and  Heterogeneous catalyst.

Answer 1

Homogenous catalyst– when reactants and catalyst are in same phase. 

e.g. 2SO₂(g) + O₂(g) →2SO₃(g) catalyst NO(g) 

Heterogeneous catalyst– the catalytic process in which the reactants and catalyst are in different phase. 

e.g. SO₂ + O₂ → 2SO₃(g) catalyst V₂O_5(s)
