Question: Which of the following statements about chemisorption is true? (2022)

Options:

  1. It is a reversible process
  2. It involves the formation of strong chemical bonds
  3. It occurs at low temperatures
  4. It is independent of the nature of the adsorbate

Correct Answer: It involves the formation of strong chemical bonds

Exam Year: 2022

Solution:

Chemisorption involves the formation of strong chemical bonds between the adsorbate and the surface, making it generally irreversible.

Questions & Step-by-Step Solutions

Which of the following statements about chemisorption is true? (2022)
  • Step 1: Understand what chemisorption means. It is a process where a substance (called the adsorbate) sticks to a surface (like a solid) by forming strong chemical bonds.
  • Step 2: Recognize that these bonds are much stronger than those formed in physisorption, which is a different type of adsorption that involves weaker forces.
  • Step 3: Note that because the bonds in chemisorption are strong, the process is usually irreversible. This means once the adsorbate is attached, it does not easily come off the surface.
