Question

Is chemisorption reversible or irreversible?

Answer 1

Chemisorption: Chemisorption or Chemical adsorption is a type of Adsorption.

• Adsorption of atoms, ions, or molecules from a gas, liquid, or soluble solids to a surface is called adsorption.
• Chemical adsorption (Chemisorption) and physical adsorption (Physisorption) are two types of adsorption.
• Chemical adsorption is a type of adsorption in which the surface and the adsorbent undergo a chemical interaction.
• In chemical adsorption, new chemical bonds (ionic or covalent) are formed at the contact surface of the adsorbent and the adsorbent.
• This can be considered an irreversible process due to the formation of new chemical bonds.
• Macroscopic phenomena such as corrosion, as well as microscopic effects related to heterogeneous catalysis, where the catalyst and reactant are in different phases, are examples.
• Hence, Chemisorption is an irreversible process.
