Question
Chemistry Question on Adsorption
Powdered substances are more effective adsorbents than their crystalline form because
A
adsorption is an exothermic process
B
they become inert and do not react with the adsorbate
C
the extent of adsorption increases with increase in surface area of the adsorbent
D
adsorption is more if the size of adsorbent is small.
Answer
the extent of adsorption increases with increase in surface area of the adsorbent
Explanation
Solution
Finely powdered substances have large, porous surface areas, hence act as better adsorbent.
