Algorithm for Solution of Complex Reactions

In complex reaction systems consisting of combinations of parallel and series reactions, the as ailability of software packages (ODE solvers) makes it much easier to solve problems using moles or molar flow rates Fj rather than conversion. For liquid systems, concentration is usually the preferred variable used in the mole balance equations. The resulting coupled differential mole balance equations can be easily solved using an ODE solver. In fact, this section has been developed to take advantage of the vast number of computational techniques now available on personal computers (Polymath). For gas systems, the molar flow rates are usually the preferred variable in the mole balance equation. 

We begin by writing mole balance equations in varitdiles other than conversion. Nf, C , Fi- Table 6-1 gives the forms of the mole balance equation we shall use for complex reactions where and tb are the net rates of formation of A and B. 

These are the forms of ihe mule balances we will use for multiple reactions.
