摘要：

In this paper, the Langmuir kinetics rate expression, which has gained currency in modeling O-2/N-2 mass transfer in carbon molecular sieve adsorbents, is derived, starting from a ''surface barrier'' model of diffusion under a chemical potential gradient; this provides a physical basis for the use of mass-action rate laws to describe diffusion processes.
