प्रश्न
Physisorption is reversible while chemisorption is irreversible. Why ?

उत्तर
Physisorption takes place with the help of non-covalent bonding between an adsorbate and an adsorbent; it makes the process reversible. Chemisorption, on the other hand, takes place with the help of covalent bonding; it makes the process irreversible.
