Abstract. A first order, reversible kinetic mechanism is used to model the process of chromatography. Under certain assumptions, the model yields results that are pedagogically useful. These results are derived from initial assumptions. While the model is certainly a very simplified one, it is effective to use when teaching young students or non-science majors about the role that intermolecular forces play in chromatographic separations. For students of physical chemistry, the model allows for a connection between reversible, first order kinetics and a familiar, real world example.
