Question

five difference between adsorption and absortion

​

Answer 1

Answer:

Absorption: (1) Absorption of substance into a cell or tissue usually occurs through the general surface of the cell.

(2) The rate and process of absorption depend on a number of factors like the concentration of the substance, surface area and duration of contact, and solubility of material.

(3) The substance that is taken in is termed absorbate, whereas the substance that take in the absorbate is term absorbent.

(4) Absorption takes place due to the presence of empty spaces within the molecules of absorbate.

(5) Absorption is an endotheric process where the heat energy of the system increases after taking in new molecules.

Adsorption: (1) This is the ability of solid particles/surface to attract the molecules of liquid and gas towards their surface after they come in contact with the molecules.

(2) Adsorption is a surface phenomenon where the molecules from a layer of adsorbate around the adsorbate around the adsorbent.

(3) Adsorption is affected by a number of factors depending on the nature of the substance involved.

(4) Some common factor includes pressure, temperature, area of contact, and the nature of adsorbent and the adsorbate.

(5) The process of Adsorption is always exothermic as it leads to decrease in the residual forces on the surface of the adsorbate.
