Question

Physical Adsorption is multilayered while chemical adsorption is monolayered

Answer 1

Thisis because phyisioadsorbtion is froum from vander waals force where as the chemical adsorption is form by chemical bonding.
physisorption forms multimolecular layer because the gas can be adsorbed one over the other by the vander waals forces, and they are (multimolecular layers) are formed under high pressure whereas in chemisorption is unimolecular because the chemical bond can be formed only with the layer of molecules coming in direct contact with the surface of the adsorbent hence chemisorption. is unimolecular

Answer 2

Answer:

Explanation:physisortion is formed by Vander wall forces which is actually a very weak forces due to which the process becomes reversible & physisortion get multilayer whereas chemisorption is formed by chemical bond which is stronger bond due to which the process becomes irreversible & chemisorption restricted to monolayer.
