Question

Chemisorption is ______.

Options

• multimolecular in nature

• reversible

• often highly specific and directional

• not very specific

Answer 1

Chemisorption is often highly specific and directional.

Explanation:

Chemisorption involves the formation of strong chemical (valence) bonds between the adsorbate and the surface, making it highly specific and directional. It is generally irreversible, occurs as a monolayer, and requires activation energy. Unlike physical adsorption, chemisorption is not multimolecular and tends to form a single layer due to the nature of chemical bonding.
