MHT CET 2022 Chemistry question

Not in JEE Main or NEET syllabus

Which of the following is NOT a characteristic of chemisorption?

(A)Heat of adsorption is in the range of 40 – 200 kJ
(B)It is specific
(C)It is irreversible
(D)Formation of multimolecular layer of adsorbateCorrect

Answer: (D)

Solution

Chemisorption involves formation of chemical bonds between adsorbate and adsorbent. Its characteristics are: high enthalpy of adsorption (about 40–400 kJ , so the range in (A) is acceptable), high specificity (only certain gases are chemisorbed on a given surface), irreversibility, increase with
