Question:
Powdered substances are more effective adsorbents than their crystalline form because
Powdered substances are more effective adsorbents than their crystalline form because
Updated On: Jul 6, 2022
- adsorption is an exothermic process
- they become inert and do not react with the adsorbate
- the extent of adsorption increases with increase in surface area of the adsorbent
- adsorption is more if the size of adsorbent is small.

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Finely powdered substances have large, porous surface areas, hence act as better adsorbent.

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.
