### Key Equations

The following is a list of important equations used in voltammetry. For each equation you should (a) know the context where the equation applies, (b) the meaning for each of the equationâ€™s variables, including typical values, and (c) how to use the equation to solve problems.

**Nernst Equation**

For the redox reaction OX + *ne*^{-} \(\rightarrow\) RED, the Nernst equation is

\[ E = E^{\textrm{o}}_{\textrm{OX} / \textrm{RED}} - \frac{0.05916}{n} \log { \frac { \left[\textrm{RED}\right] }{ \left[\textrm{OX}\right] } } \]

**Randles-Sevcik Equation**

For the redox reaction OX + *ne*^{-} \(\rightarrow\) RED, the Randles-Sevcik equation is

\[ {i}_{p} = {\left (2.69 \times {10}^{5} \right)} {n}^{3/2} A {D}^{1/2} {\nu}^{1/2} {C}_{OX} \]
