I) Write the expression for the Freundlich adsorption isotherm for the adsorption of gases on solids in the form an equation.

II) What are the dispersed phase and dispersed medium of butter?


III) A delta is formed at the meeting place of sea and river water. Why?



I) The expression for the Freundlich isotherm for the adsorption of gases on solids is:



It can be written as: (taking log on both sides)





Where,


x – mass of the gas adsorbed


m – mass of adsorbent


p – pressure


k and n – values dependent on the adsorbent and gas at particular temperature.


II) The dispersed phase in butter is liquid (water) and dispersed medium is solid.


III) As the river reaches the sea or ocean, it delivers all its fine particles and material at the mouth of it. This creates a fan-like track in the soil which distributes the river into various channels called as distributaries. This fan-shaped appears like a triangle called as a delta.
