type of catalysis

What are the two broad types of catalysis?

• Solid and Liquid

• Chemical and Biological

• Homogeneous and Heterogeneous

• Fast and Slow

In which type of catalysis do the reactants and the catalyst form a single phase?

• Homogeneous catalysis

• Heterogeneous catalysis

• Liquid catalysis

• Solid catalysis

What is an example of a reaction that involves homogeneous catalysis?

• Oxidation of So2 to So3

• Habers process

• Keto-enol transformation

• Inversion of sugars

In which type of catalysis do the reactants form one phase but the catalyst forms a different phase, usually solid?

• Liquid catalysis

• Heterogeneous catalysis

• Homogeneous catalysis

• Gas catalysis

What is an example of a reaction that involves heterogeneous catalysis?

• Habers process

• Inversion of sugars

• Keto-enol transformation

• Oxidation of So2 to So3

What is acid-base catalysis?

• The addition of an acid or a base to a chemical reaction to speed up the reaction without consuming the acid or base

• The removal of an acid or a base from a chemical reaction to slow down the reaction

• The addition of an acid or a base to a chemical reaction to slow down the reaction

• The removal of an acid or a base from a chemical reaction to speed up the reaction

What is an example of a reaction that involves acid-base catalysis?

• Oxidation of So2 to So3

What is enzyme catalysis?

• The removal of an enzyme from a chemical reaction to speed up the reaction

• The removal of an enzyme from a chemical reaction to slow down the reaction

• The addition of an enzyme to a chemical reaction to slow down the reaction
