उत्तर
Adsorption is a surface phenomenon. Therefore, the process of adsorption is directly proportional to the surface area available for adsorption to take place. Both physisorption and chemisorption increase with an increase in the surface area. Powdered substances have large surface areas. Hence, powdered substances are more effective adsorbents.
