摘要
The Langmuir equation describing the adsorption kinetics of particles on surfaces is obtained from non-equilibrium thermodynamics. For this purpose, we consider that the adsorption phenomenon consists of two different processes, namely, diffusion and transition through a potential barrier. The latter is treated using the theory of internal degrees of freedom.
