The parameter Eo in eq. (4.4-5) is the mean characteristic energy of the solid toward the reference vapor, and a is the variance in the Gaussian distribution (moleVJoule ). The parameters q and n are distribution parameters, and they affect the mean characteristic energy and the variance of the distribution. For the shifted Gamma distribution (4.4-6), the mean and the variance are ... 

To evaluate the intergral (4.5-1), the parameters of the local isotherm must be expressed in terms of the micropore half width, x. The parameter n is usually regarded as a constant. The parameter Eq is the characteristic energy of the reference vapor, and it is found by the small angle X-Ray scattering to follow the following relationship with the micropore half width... 

If, instead of the normal boiling point, another reference vapor pressure is available, can be adjusted in a way that the reference point is met. If no reference point is available, can be estimated. In this case, the accuracy of Eq. (3.44) is, of course, significantly lowered as mentioned above. 

If two adsorbates fill the same adsorption volume their adsorption mtentials will differ only because of differences in their molecular >ioperties. The ratio of adsoiption potentials was assumed by Dubinen SS] to be a constant which he deflned as an affinity constant (P) since t is a measure of the relative affinities of different molecules for a surface. Uring benzene as a reference vapor the affinity ratios for other vapors were determined [56].
