ABSTRACT: During studying the
heat capacity of metals and brightening more than the original Lena’s image,
the temperature increasing term obtained in binomial expansion is transformed
into the adsorption increasing term and thereafter we have derived the total
adsorption rate equation with it. In the first layer the quantization does not
occur and from 2nd layer to nth layer the quantization occurs.
So as to get the total adsorption rate equation we add the quantized terms of
the second to nth layers to the non-quantized term of the first
layer. All terms are based on the unit surface sites. Instead of the unit
surface sites, the new adsorption site term appears in the denominator of the adsorption
equation. Hence the adsorption equations come out much better than BET
equation. The surface area is also calculated through the integration of the
adsorption isotherm equation excluding the first layer adsorption equation from
the inflection point to the wanted relative pressure.
