Q) Discuss the mechanism and thermodynamic aspect of adsorption?
Answers
Answer:
The most important appli- cation of thermodynamics to adsorption is the calculation of phase equilibrium between a gaseous mixture and a solid adsorbent. The basis for thermodynamic calculations is the adsorption isotherm, which gives the amount of gas adsorbed in the nanopores as a function of the external pressure.
Explanation:
It is an exothermic process which means that energy is liberated during this process. The reason behind this is that when adsorbate molecules are adsorbed on the surface, freedom of movement of molecules become restricted and this results in a decrease in entropy. ...
When we increase the surface area of the adsorbent there is an increase in the adsorption of gases. This is because when we increase the surface area there is more number of adsorbing sites. So finely divided solids and some porous substances are good adsorbents.
