Question

Wht physical adsorption is multilayered and chemical adsorptions is monolayered

Answer 1

In physical adsorption occurs due to inter-molecular attractive forces between the adsorbate and adsorbent.If the size of adsorbent pores is close to the size of adsorbate molecules, multilayer adsorption takes place i.e adsorption takes place until all the pores are filled with adsorbate molecules.

Answer 2

Physical adsorption occurs due to inter-molecular attractive forces between the adsorbate and adsorbent. Therefore it is multilayer.

Whereas, in chemisorption; chemical bonds are formed between adsorbate and adsorbent molecules. Therefore, it is monolayer.
