This app simulates a one-electron electrochemical reaction under galvanostatic control: $$O + e^- \overset{k_f}{\underset{k_r}{\leftrightarrows}} R$$ I wrote tutorials describing this simulation here. I hope that this tool increases the accessibility of simple electrochemical simulations. Please contact me with any questions, comments, or suggestions!

To save an image and extract the x-y data, use the first two buttons in the toolbar.

$C_O =$ $\text{mol/cm}^3$, initial concentration of $O$
$D =$ $\text{cm}^2 \text{/s}$, diffusion coefficient of both $O$ and $R$
$j =$ $\text{A/m}^2$, applied current
$n =$ , $e^-$ per reaction
$\alpha =$ , charge transfer coefficient
$k_0 =$ $\text{cm/s}$, electrochemical rate constant
$L =$ , simulation resolution

Simulation timescale, $\tau =$ $\text{h}$
