Questions and Answers

Explain the difference between intermolecular forces and intramolecular forces in the context of surface chemistry.

Intermolecular forces are forces of attraction or repulsion between molecules, while intramolecular forces are the forces that hold the atoms within a molecule together.

What are the causes of adsorption?

The causes of adsorption include van der Waals forces, electrostatic forces, and chemical bonding between the adsorbate and the adsorbent surface.

Discuss the distinction between reversible and irreversible adsorption.

Reversible adsorption is when the adsorbate can be easily removed from the adsorbent surface, while irreversible adsorption is when the adsorbate forms strong chemical bonds with the adsorbent and is difficult to remove.

Explain the types of isotherms used to model adsorption.

<p>The types of isotherms used to model adsorption include Freundlich adsorption isotherm, Langmuir adsorption isotherm, and BET adsorption isotherm.</p> Signup and view all the answers

What factors can affect adsorption?

<p>Factors affecting adsorption include the nature of the adsorbate and adsorbent, temperature, pressure, and the presence of other chemicals in the system.</p> Signup and view all the answers
