Question

Why are founded substances more effective adsorbents than their crystalline forms?

Answer 1

Answer:

Powdered substances are more effective adsorbents than their crystalline forms because when a substance is powdered, its surface area increases and physisorption is directly proportional to the surface area of the adsorbent.

Explanation:

Answer 2

Answer:

Finely divided small size particles provide a large surface area compared to a large particle. Hence adsorption is to a greater extent. This increases the catalytic activity to a greater extent.
