Which of the following is true about chemisorption?
It is a reversible process
It occurs only at low temperatures
It is specific in nature
It occurs only on the surface of a solid
Chemisorption is a type of adsorption where the adsorbate molecules are strongly held by the surface of the adsorbent through chemical bonds. It is specific in nature as it involves the formation of specific chemical bonds between the adsorbate and the adsorbent. Chemisorption is not a reversible process and occurs at high temperatures.
