Answer:
Characteristics of adsorption :
(1) It involves intermolecular forces.
(2) Weak van dar Waals forces give rise to physical adsorption
(3) Strong chemical bonding forces give rise to chemical forces.
(4) Adsorption is exothermic.
(5) In case of physisorption, adsorption decreases with the increase in temperature while in chemisorption it increases.
(6) It is applicable in many industrial processes.
