The Total solution for NCERT class 6-12
Give reason why a finely dividedsubstance is more effective as an adsorbent.
Adsorption is a surfacephenomenon. Therefore, adsorption is directly proportional to the surface area.A finely divided substance has a large surface area. Both physisorption andchemisorption increase with an increase in the surface area. Hence, a finelydivided substance behaves as a good adsorbent.
