Formula Used
The standard electrochemical rate constant ($k_0$) is derived from the exchange current using the fundamental Butler-Volmer kinetics framework. The primary equation implemented is:
$$k_0 = \frac{i_0}{n F A C}$$
Where $i_0$ represents the exchange current, $n$ is the number of electrons transferred, $F$ is the Faraday constant ($96485$ C/mol), $A$ is the electrode area, and $C$ is the bulk concentration.
