Question

Define adsorption
write any two features which distinguishes physisorption from chemisorption​

Answer 1

Answer:

The process by which a solid holds molecules of a gas or liquid or solute as a thin film is called adsorption.

For physisorption, under appropriate conditions, gas phase molecules can form multilayer adsorption. In chemisorption, molecules are adsorbed on the surface by valence bonds and only form monolayer adsorption.
