The correct statement regarding chemisorption is

Options

  1. AIt is a multilayered adsorption
  2. BThe process is reversible in nature
  3. CThe process is not specific in nature
  4. DEnthalpy of adsorption is in the range of 80-240 kJ mol ⁻¹

Correct answer

D. Enthalpy of adsorption is in the range of 80-240 kJ mol ⁻¹

Step-by-step solution

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 ~K ) (v) It is caused by chemical bond formation.
