bet equation derivation,Thermodynamic Derivation. The adsorption process between gas phase molecules, A, vacant surface sites, S, and occupied surface sites, SA, can be represented by the equation, assuming that there are a fixed number of surface sites present on the .freundlich isotherm equationBET Derivation. Consider a surface: Definition: q 0, q 1, ., q n = Surface .
The concept of the theory is an extension of the Langmuir theory, which is a theory for monolayer molecular adsorption, to multilayer adsorption with the following hypotheses: 1. gas molecules physically adsorb on a solid in layers infinitely;2. gas molecules only interact with adjacent layers; and
