12 December 2014 1 8K Report

The expression of Rct derived by Butler-Volmer equation is Rct = RT/nFio

where

io= exchange current density

F= Faradays constant

T= temperature

R= gas constant

n= number of electrons involved.

In Randles circuit, the resistance parallel to the double layer capacitor represent the value of charge transfer resistance Rct.
