Adsorption axioms

The second and third axioms specify Nv(p) and N/(p), once the amounts of adsorption sites are known ... 

Much more complex is to specify the evolution of Nm./ as adsorption proceeds. We assume the following axioms ... 

In view of the ability of eq. (4) to describe adsorption in the monolayer region, we assume that C M isotherm must reduce to the ABSB equation when s = 0 or b = 0. The following axiom allows this need to be satisfied ... 

On intuitive grounds one realizes that the combination of axioms from (C Ml) to (C M8) leads to clusters whose surface area increases significantly, for e, b >0, as the adsorption proceeds. In next part it will be shown that this increase results in a divergence of N/(p) at a certain pressure p. The last axiom is a way to deal with this divergence ...
