Answer 1

CONCEPT:

Chemisorption

Chemisorption, or chemical adsorption, involves the formation of a chemical bond between the adsorbate and the surface of the adsorbent.
This type of adsorption is typically highly specific to the adsorbate and adsorbent involved.
Chemisorption usually has a high enthalpy of adsorption due to the chemical bond formation.
It is generally irreversible because the process involves breaking and forming of chemical bonds.

EXPLANATION:

We know that chemisorption involves specific interactions between the adsorbate and the surface, which means it is highly specific.
It also has a high enthalpy of adsorption due to the formation of strong chemical bonds.
Additionally, chemisorption is generally irreversible because breaking these bonds requires significant energy.
Therefore, the statement "Lack of specificity" does not describe chemisorption.

Therefore, the correct answer is Lack of specificity.
