+## Simple Batch Rector
+
+This is a simple model of an batch stirred tank reactor (BSTR). Assuming a reaction system of
+
+```math
+\mathrm{A} \rightarrow \mathrm{B}
+```
+
+the following system of differential equations can be derived:
+
+
+```math
+\begin{align*}
+\frac{\mathrm{d} \, c_\mathrm{A}}{\mathrm{d} \, t} &= - k \, c_\mathrm{A} \\
+\frac{\mathrm{d} \, c_\mathrm{B}}{\mathrm{d} \, t} &= k \, c_\mathrm{B}
+\end{align*}
+```
+
+| Name  | Unit  | Description |
+| :--- | :--- | :--- |
+|``c_\mathrm{A}``| ``\mathrm{mol \, L^{-1}}`` | Molar concentration of species A |
+|``c_\mathrm{B}``| ``\mathrm{mol \, L^{-1}}`` | Molar concentration of species B |
