The two models are shown to have input multiplicity behaviour. Though the conventional steady-state operation gives an identical yield of product B for both the reactions under certain parameters values, the input multiplicity behaviour (yield <i>vs</i> residence time) is different for the two reactions. Further, the effect of feed concentration cycling on the average yield of B is compared under input multiplicity.</span></span></span>
