The physical adsorption is the type of adsorption in which vander waals forces are present.
Explanation:
Adsorption
It is the phenomenon in which the concentration of substance is more on surface than in bulk .
Adsorbate : The substance that get adsorbed .
Adsorbent : The surface on which the adsorption occurs .
The adsorption is of two types :
Physio-adsorption
Chemio-adsorption
Physio adsorption
It is the type in which the weak vander wall forces are present .
It has low enthalpy of adsorption.
With increase in temperature , the extent of this type of adsorption decreases .
It is non specific in nature
Chemio-adsorption
It has strong force of attraction .
It has high enthalpy of adsorption.
It is highly specific in nature .
With increase in temperature , it increases and then it decreases .
