 This app allows you to control different operating parameters (e.g., feed temperature and volume flow rate) and study the dynamic behavior of a CSTR. Furthermore, you are able to define your own power-law reactions and scripts to change input parameters.

Be aware that enthalpy of reaction ( `"dH"` ) and reaction rate is calculated based on the first component written in each `{}`. In this case, we also set initial values for concentrations and reactor temperature by specifying `"initial"` (optional). If specified, values in `initial["C"]` are assigned to each component in `"C0"` at t=0.
