Levich constant

A Levich constant (B) is often used in order to simplify the Levich equation. Furthermore, B is readily extracted from rotating disk electrode experimental data.

The B can be defined as:

$$B= (0.620) n F A D^\frac{2}{3}v^\frac{-1}{6}C$$

where
 * n is the number of moles of electrons transferred in the half reaction (number)
 * F is the Faraday constant (C/mol)
 * A is the electrode area (cm2)
 * D is the diffusion coefficient (see Fick's law of diffusion) (cm2/s)
 * v is the kinematic viscosity (cm2/s)
 * C is the analyte concentration (mol/cm3)
