A substance is a better adsorbent in its finely powdered form as compared to crystalline form
\( \mathrm{P} \) because:

W
(1) adsorption is an exothermic process.
(2) In the powdered state adsorbent becomes inert and does not react with adsorbate.
(3) adsorption is a surface phenomenon.
(4) adsorption varies directly with size of particles of adsorbent.
