Behaviour at long residence times

This situation stems from the peculiarities of the simplest representations of autocatalytic reactions, as discussed previously. In chapter 2, we considered a kinetic scheme in which the autocatalysis proceeded in parallel with an uncatalysed step A - B. We can expect that the inclusion of such a step here will have a strong influence on the behaviour at long residence times, as there will then always be a route from A to B. We consider this in the next section. 

When the model of the previous section is augmented by a direct step from A to B, the scheme becomes

Figure 3(c) A further increase of the catalyst inlet concentration leads to the pattern in Fig. 3c. The behaviour at long residence-times is now quite different.
