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:

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

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)
