Question:
Which of the following conditions are favourable for chemisorption?
Which of the following conditions are favourable for chemisorption?
Show Hint
Chemisorption is stronger and more specific than physisorption, and high temperature and pressure help overcome the activation energy barrier for bond formation.
Updated On: Apr 23, 2025
- \text{Low temperature and high pressure}
- \text{High temperature and low pressure}
- \text{High temperature and high pressure}
- \text{Low temperature and low pressure}
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
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).
