The rate of adsorption is governed by the rate of arrival of molecules at the surface and the proportion of incident molecules which undergo adsorption. The rate of adsorption (per unit area of surface) as a product of the incident molecular flux, F , and the sticking probability , S .
R(ads) = S . F [molecules m-2 s-1 ]

In the case of adsorption, a relatively small quantity of one substance would get attached to the surface of the bulk substrate as a result of various types of interactions.
In regards to materials that we have learned in this class, adsorption is the process in which reactants sit on surface of catalyst.
