Chemisorption is the adsorption by chemical bonding. Whereas physisorption can usually be reversed by adding heat, chemisorption cannot. Because chemisorption is a chemical process, new chemical bonds must be made, which involves activation energy barriers and time.

Explanation:

Physical Adsorption 

1. This is usually takes place at low temperature and decreases with increase in temperature.

2. The forces of attraction holding the adsorbate are Vander Waal’s forces

3. Heat of adsorption is low

4. It is reversible

5. It is not very specific

6. It forms multimolecular layer

7. It does not require any activation energy

Chemical Adsorption 

1. This takes place at high temperature

2. The forces of attraction holding the adsorbate are chemical bond forces

3.Heat of adsorption is high

4. It is irreversible

5. It is highly specific

6. It forms monomolecular layer

7. It requires activation energy.
