Difference between physical adsorption and chemical adsorption
Answers
Explanation:
Chemical Adsorption also known as chemisorptions is a kind of adsorption which involves a chemical reaction between the surface and the adsorbate whereas Physical adsorption is a kind of adsorption which attaches the target substance on a chip as a result of hydrogen bonding, van der waals forces, electrostatic forces ...
Answer:-
✔️ Chemical adsorption:-
▪️In chemical adsorption the forces of attraction between adsorbate and adsorbent are chemical forces i.e through bond formation.
▪️It is irreversible in nature.
▪️ It takes place at high temperature.
▪️ It forms only monomolecular layer.
✔️Physical Adsorption:-
▪️In physical adsorption the forces of attraction between adsorbate and absorbent are Van der Waal’s forces.
▪️It is reversible in nature.
▪️It generally takes place at low temperature.
▪️It forms multi-molecular layers of adsorbate.
