Question

Distinguish between Homogeneous and Heterogeneous catalysis. Give on example of each.

Answer 1

Homogeneous catalysis: catalysis in which the reactants and catalyst are in same phase...

Example: 2SO₂(g) + O₂(g) -----No(g)---> 2SO₃ (g)


Heterogeneous catalysis: catalysis in which the reactants and catalyst phases are differ from each other..

Example: 2SO₂(g) + O₂(g) -----pt(s)--->2SO₃ (g)
