Random sequential adsorption of mixtures

We present a theory that describes the random sequential adsorption of a two-component mixture of hard disks of greatly differing diameters on a flat surface. The jamming limit of the large disks can be obtained from a numerical solution of two coupled first-order differential equations. In the special case of a mixture of disks and point particles the equations take on a simple form, and the kinetics and jamming limit can be determined essentially exactly for certain ranges of the adsorption rate constants.
