Which of the following is not a characteristic of chemisorption?

Options

  1. AAdsorption is highly specific
  2. BHeat of adsorption is around (400 ~kJ ~mol ⁻¹ )
  3. CThe process is irreversible
  4. DIt forms multimolecular layer

Correct answer

D. It forms multimolecular layer

Step-by-step solution

Options (a), (b) and (c) truely explain the characteristics of chemisorption. But option (d) is not because is chemisorption a single layer of adsorbate gets formed on the surface of absorbent.
