Electrical vs diffusive force

WebFick's first law of diffusion relates the diffusive flux to the concentration gradient as follows: (1) where J is the diffusive flux (mol m 2 s −1 ), D is the diffusion coefficient (m 2 s −1 ), c is the concentration (mol m −3 ), and x (m) is the spatial dimension. The negative sign indicates that the diffusive fluxes are directed against ... WebSep 15, 2024 · Here, electrical mobility is related to the diffusion coefficient of the sample species through the following equation. It is called the Einstein relation. µ = (q/kT)D. In …

WebThe system clay lattice-exchangeable cations-solution can be looked upon as forming a complex electrical double layer, known as the Helmholtz double layer, the inner layer being the surface of the lattice carrying the negative charge (Fig. 9.15) and the outer layer being composed of two parts—a positive layer due to the cations bound to ... Web(189), the electric double layer around a spherical particle exhibits qualitatively the same properties as for the planar interface. In particular, after an initial abrupt drop, the electric potential decreases exponentially with the normalized distance a/Le.
