It has previously been shown (Tanner et al., 1985) that biochemical and chemical reaction processes of the Type A → B → C can lead not only to kinetic hysteresis between the rate of formation of C and the concentration of species B in batch processes, but also hysteresis between those variables in a closed, imperfectly mixed (two zone) batch reactor. Furthermore, crossplotting the intermediate reactant, B , in one region of the poorly mixed reactor against B from the other major region leads to a clockwise hysteresis curve which is defined by both its area and the coordinate phase angle. This paper shows that the earlier analysis (Tanner et al., 1985) can be extended to the more general system A → B , where A in one region of the vessel is crossplotted against A measured in the other region. With an initial concentration of A * in one zone equal to its highest concentration, the inscribed area double‐valued crossplot of A , uniquely defines the system in terms of the inter‐vessel flowrate to reaction rate constant ratio, D/k .
