(i) It arises due to vander Waals forces and |
(ii) it is reversible. Identify the correct statement that describes the above adsorption process: |
A) Enthalpy of adsorption is greater than \[100 \text{kJ}\,\text{mo}{{\text{l}}^{\text{-1}}}.\]
B) Adsorption is monolayer.
C) Adsorption increases with increase in temperature.
D) Energy of activation is low.
Correct Answer: D
Solution :
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)You need to login to perform this action.
