Before revision:  Here, our main application is for enumerating small multistationary continuous-flow stirred-tank reactors (CFSTRs), which are networks in which all chemical species take part in the inflow and outflow. Recent work of the first author presented a simple characterization of the one-reaction CFSTRs that admit multiple positive steady states. Here we consider the two-reaction CFSTRs. We enumerate all 386 bimolecular and reversible such networks.
After revision:  Additionally, our work provides sufficient conditions for establishing multistationarity by way of atoms and moreover reduces the problem of classifying multistationary CFSTRs to that of cataloging atoms of multistationarity. As an application, we enumerate and classify all 386 bimolecular and reversible such networks.
