Lability of complexes in steady-state finite planar diffusion

The analytical solution of the reaction-diffusion problem of a species forming a complex (with any association and dissociation rate constants) in solution and disappearing at an active planar surface is presented for a finite diffusion region where the system reaches steady state under diffusion li...

description The analytical solution of the reaction-diffusion problem of a species forming a complex (with any association and dissociation rate constants) in solution and disappearing at an active planar surface is presented for a finite diffusion region where the system reaches steady state under diffusion limited conditions.
