What is randles sevcik equation?

Randles-Sevcik equation is a fundamental equation in electrochemistry that describes the behavior of an ideal polarized electrode. It is used to interpret cyclic voltammetry data and to determine the electrochemical parameters of a system.

The equation relates the current passing through an electrode to the applied potential and the properties of the electrode/electrolyte interface. It is given by the following form:

i = nFkCv

Where:

• i is the current passing through the electrode
• n is the number of electrons transferred in the redox reaction
• F is the Faraday constant
• k is the rate constant of the redox reaction
• C is the concentration of the redox species
• v is the scan rate

The Randles-Sevcik equation can be used to calculate the diffusion coefficient of the redox species, the charge transfer resistance, and other important electrochemical parameters. It is widely used in research and industry for the analysis of electrochemical processes.
