The two characteristics of Chemisorption are:

a) In Chemisorption which is highly specific in nature, the adsorbate and adsorbent get attached by chemical bonds which are either covalent or ionic in nature.

b) High activation energy is required and high temperature is also favourable.

c) Chemisorption increases with the increase in surface area which results in more number of active sites.
