more to come: examples of reactors, how they are used, etc.
A '''chemical reactor''' is a [[process unit]] which combines one or more [[chemical]]s into another by promoting a [[chemical reaction]]. Reactors can be run as [[flow system]]s or as [[batch system]]s.

The [[design equation]] for a chemical reactor is based directly on the [[general balance equation]]

:<math>F_{j0} - F_j + \int^V{r_jdV} = \frac{dN_j}{dt}</math>

where
:j is a specific species (chemical) in the system
:F<sub>j0</sub> is the molar flow rate into the system of species j
:F<sub>j</sub> is the molar flow rate out of the system of species j
:r<sub>j</sub> is the [[rate equation|rate of dissapearance]] of species j
:V is [[volume]] in which the reactor takes place
:N<sub>j</sub> is the number of [[mole]]s of species j

The design equation is always performed on the [[limiting reactant]] of a reaction.
