CBSE Class 12-science Answered
sir plz explain the second sentence of the statement within semicolon("")
Adsorption is a surface phenomenon: During the phenomenon of
adsorption the adsorbate molecules are held on the surface of the
adsorbent by weak or strong (co- valent bond) forces.
"Therefore heat is
liberated during adsorption.
It is further more clear from the fact that finely divided adsorbents are good
adsorbents, because free forces increase on subdivision."

When we powdered the adsorbent the active sites becomes more and more adsorbate can attached with the bonds.more bonds formation means more energy.
