A particular adsorption process has the following characteristics: (i) It arises due to vander Waals forces and (ii) it is reversible. Identify the correct statement that describes the above adsorption process:
Text Solution
Verified by ExpertsThe correct answer is:
D
Adsorption aries due to Vander waal forces & reversible, hence it should be physisorption (physical adsorption).
(i) Enthalpy of physisorption is low (20 – 40 kJ/mol)
(ii) In physisorption multimolecular layer form.
(iii)
Physisorption decreases with increase in temperature.
(iv) Physisorption required number activation energy.
