Catalysis quiz

The reaction where the reactants and the catalyst are in same phase takes place is known as

• Homogeneous catalysis

• Heterogeneous catalysis

• Equilibrium reaction

• No reaction

Homogeneous catalysis is usually takes place in

• Solid phase

• Liquid phase

• Gas phase

Find the different one from the following

• Acid base catalysis

• Enzyme catalysis

• Electrochemical reaction

• Polymerization

Addition of acid or base in catalytic reaction leads to
