Of the two types of semibatch reactors, we focus attention primarily on the one with constant molar feed. A schematic diagram of this semibatch reactor is shown in Figure 6-5. We shall consider the elementary liquid-phase reaction
A + B → C

in which reactant B is slowly added to a well-mixed vat containing reactant A.
A mole balance on species A yields

Three variables can be used to formulate and solve semibatch reactor problems: the concentrations, ...
