| Abstract
| - In this work, an improved solution for multilayer adsorption of linear species is presented. The particularcase of multilayer dimer adsorption is dealt with in detail, and a new adsorption isotherm is obtained fordetermination of surface area and adsorption energy from experiments. From the comparison between thenew isotherm and the standard Brunauer−Emmett−Teller (BET) formalism, it arises that the monolayervolume, vm (or the surface area, A), can be up to 1.5 times larger than the one from the BET model. Theproposed model is simple and easy to apply in practice and leads to new values of surface area and adsorptionheat. Physically, these advantages are a consequence of properly considering the configurational entropyof the adsorbate.
