Formation of multimolecular layer of adsorbate.

Vedclass · Answer

(D) Chemisorption involves the formation of chemical bonds between the adsorbate and the adsorbent. Due to the formation of chemical bonds,it is highly specific and irreversible in nature. The heat of adsorption for chemisorption is high,typically in the range of $40-200 \ kJ \ mol^{-1}$. However,chemisorption results in the formation of a unimolecular layer,not a multimolecular layer. Multimolecular layer formation is a characteristic of physisorption.

Which of the following is $NOT$ a characteristic of chemisorption?
