प्रश्न
Give reason why a finely divided substance is more effective as an adsorbent.
Advertisements
उत्तर
Adsorption is a surface phenomenon. Therefore, adsorption is directly proportional to the surface area. A finely divided substance has a large surface area. Both physisorption and chemisorption increase with an increase in the surface area. Hence, a finely divided substance behaves as a beneficial adsorbent.
