WebTools. The Nernst–Planck equation is a conservation of mass equation used to describe the motion of a charged chemical species in a fluid medium. It extends Fick's law of diffusion for the case where the diffusing particles are also moved with respect to the fluid by electrostatic forces. [1] [2] It is named after Walther Nernst and Max Planck . WebMass transfer limitations are most common for fast binding reactions, as diffusion limits the association rate. Here are three common ways one can limit mass transfer effects in kinetic data: 1) Higher flow rates.
