absorbtion depend on some factors like temperature,pressure,surface area and nature of absorbent .
more is the surface area more is absortion .
in case of finely divided substance the surface area is increased hence absorption is more effective

Answer:Adsorption is directly proportional to the surface area as adsorption is surface phenomenon. A finely divided substance behaves like a good adsorbent because it has a large surface area. Both physisorption and chemisorption increase with an increase in the surface area.
