Question
Differentiate homogeneous and heterogeneous catalysis.
✓
Answer
Homogeneous catalysis
1. The reaction in which, the reactants, products and catalyst are present in the same phase, is called homogeneous catalysis.
2. $\underset{ }{2} SO _{2( g )}+ O _{2( g )} \stackrel{ NO _{( g )}}{\longrightarrow} 2 SO _{3( g )}$
3. Homogeneous catalysis mechanism is ex plained by intermediate compound formation theory.
Heterogeneous catalysis
1. The reaction in which the reactants, products and catalyst are present in different phases is called heterogeneous calalysis.
2. $2 SO _{2( g )}+ O _{2( g )} \stackrel{ Pt ( s )}{\longrightarrow} 2 SO _{3( g )}$
3. Heterogeneous catalysis mechanism is explained by adsorption theory.
