The correct statement regarding chemisorption is
- A It is a multilayered adsorption
- B The process is reversible in nature
- C The process is not specific in nature
- D Enthalpy of adsorption is in the range of 80-240 kJ \(\mathrm{mol}^{-1}\)
Answer & Solution
Correct Answer
(D) Enthalpy of adsorption is in the range of 80-240 kJ \(\mathrm{mol}^{-1}\)
Step-by-step Solution
Detailed explanation
Chemisorption: (i) It is highly specific in nature. (ii) It is irreversible (iii) It result into unimolecular layer. (iv) Enthalpy of adsorption is high ( \(80-240 \mathrm{~K}\) ) (v) It is caused by chemical bond formation.
