Question:
During the adsorption of Krypton on activated charcoal at low temperature
During the adsorption of Krypton on activated charcoal at low temperature
Updated On: Apr 18, 2024
- $\Delta H < 0$ and $\Delta S < 0$
- $\Delta H > 0$ and $\Delta S < 0$
- $\Delta H > 0 $ and $\Delta S > 0$
- $\Delta H < 0 $ and $\Delta S > 0$
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
During adsorption, heat is liberated hence $\Delta H$ is negative (less than zero) and entropy decreases.

Concepts Used:
Adsorption
Heinrich Kayser, the German physicist was the first to coin the term adsorption. Adsorption can be explained as a surface phenomenon where particles remain attached on the top of a material. Generally, it comprises the molecules, atoms, liquid, solid in a dissolved stage, even the ions of a gas that are attached to the surface. Much to our surprise, the consequence of surface energy i.e. adsorption is present in biological, physical, chemical, and natural systems and are used in many industrial applications.
