Diagrammatic Analysis of Nonhomogeneous Diffusion

Figure 1

(a) and (b) Diagrams representing solute diffusion between positions “” and “”: a two-path model with two transitions each and an intermediate connection (a) and a model with two independent paths of different lengths (b). design transitions, governed by rate constants , respectively. For each transition, the two directions are governed by the same rate constant. (c) and (d) Individual paths and their appendages (c) and directional diagrams connecting positions “” and “” (d) for the model of (a). The corresponding products of rate constants are shown.
