During studying theheat capacity of metals and brightening more than the original Lena’s image,the temperature increasing term obtained in binomial expansion is transformedinto the adsorption increasing term and thereafter we have derived the totaladsorption rate equation with it. In the first layer the quantization does notoccur and from 2nd layer to nth layer the quantization occurs.So as to get the total adsorption rate equation we add the quantized terms ofthe second to nth layers to the non-quantized term of the firstlayer. All terms are based on the unit surface sites. Instead of the unitsurface sites, the new adsorption site term appears in the denominator of the adsorptionequation. Hence the adsorption equations come out much better than BETequation. The surface area is also calculated through the integration of theadsorption isotherm equation excluding the first layer adsorption equation fromthe inflection point to the wanted relative pressure.
