Levich constant

A Levich constant (B) is often used in order to simplify the Levich equation.^[1] Furthermore, B is readily extracted from rotating disk electrode experimental data.

The B can be defined as:^[2]

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

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)
