question

(a) write the dispersed phase and dispersion medium of milk.
(b) why is adsorption exothermic in nature?
(c) write freundlich adsorption isotherm for gases at high pressure.

 

 

 

 

 

 

 

 

(a)milk-

 dispersed phase: liquid

 dispersion medium: liquid

(b) during the process of adsorption, molecules of adsorbate and adsorbent come closer to form physical or chemical bonds, hence, getting stabilized, in this process, heat is evolved leading to release of heat energy, making the process exothermic.

(c)

 where n > 1,mass of gas absorbed on the mass of the adsorbent at pressure p. k is constant that depends on the nature of adsorbent and the gas at a particular temperature.
