Butler-Volmer equation[edit]
Amperometry at constant potential[edit]
- Amperometry - measuring current
- Linear sweep voltammetry - measure current while increasing potential linearly with time
- The diffusion limiting current depends on the concentration gradient, which is time dependent
- To express current as a function of time, use Fick's Second Law of diffusion to derive the Cottrell equation via a Laplace transform
Cyclic voltammetry[edit]
- Cyclic voltammetry
- Linear Sweep & Cyclic Voltammetry: The Principles from the Cambridge Chemical Engineering electrochemistry group.
- Randles-Sevcik equation
- For a reversible reaction, the peak-to-peak separation is 59 mV / n, where n is the number of electrons transferred per molecule/species
- Peak positions are independent of sweep rate, ν
