Physisorption is reversible while chemisorption is irreversible. Why? – InterviewSolution

1.	Physisorption is reversible while chemisorption is irreversible. Why?
Answer» Solution : Physisorption INVOLVES weak forces between the ADSORBENT and the adsorbate while chemisorption involves the FORMATION of a chemical bond between the adsorbent and adsorbate. Once a chemical bond is formed, it is difficult to break. Therefore physisorption is REVERSIBLE but chemisorption is irreversible
