Some Relations between Macroscopic and Microscopic Adsorption Parameters

3 Some Relations between Macroscopic and Microscopic Adsorption Parameters The molar integral change of free energy at a temperature T during adsorption is [2,13] 

Besides, it is possible to show that that the relation between the enthalpy of adsorption (AH -,h) and the differential heat of adsorption (qlll ) for porous systems is [2,15,16,25] 

Now assuming that the change in entropy on adsorption is negligible in comparison with the rest of terms in Equation 6.11, and taking into account that the change in the free energy of adsorption (AGads) can be expressed by 

If the adsorbed phase is ideal, that is, T = KP, then from the definition of d
