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.

Answer:
Most commercial adsorbents rely on physical adsorption; while catalysis relies on chemisorption. ... Physical adsorption will occur under suitable temperature-pressure conditions in any gas solid system, while chemisorption takes place only if the gas is capable of forming a chemical bond with the surface.
