Question

Which of the following conditions are favourable for chemisorption?

• A. \text{Low temperature and high pressure}
• B. \text{High temperature and low pressure}
• C. \text{High temperature and high pressure}
• D. \text{Low temperature and low pressure}

Hint:

Chemisorption is stronger and more specific than physisorption, and high temperature and pressure help overcome the activation energy barrier for bond formation.

Answer 1

The Correct Option is C

Chemisorption, unlike physisorption, involves the formation of strong chemical bonds between the adsorbate and the adsorbent. This type of adsorption typically occurs at high temperatures and high pressures, as these conditions increase the rate of interaction and bond formation between the molecules. Thus, the correct answer is Option (C).
