Which of the following is NOT a characteristic of chemisorption?
Heat of adsorption is in the range of $40-200 \mathrm{~kJ} \mathrm{~mol}^{-1}$
It is specific.
It is irreversible
Formation of multimolecular layer of adsorbate.
Solution
A chemisorption layer is a unimolecular layer of molecules that forms on a solid surface through a chemical reaction between the adsorbent and adsorbate
