Multiple reactions mixed series/parallel

Systems of multiple reactions usually fall into one of four categories. These classifications are parallel, independent, series, and mixed series/parallel. Recognizing the structure of a multiple-reaction system frequently helps to identify the best approach to design or analysis. 

The multiple reactions involve parallel, series, and mixed reactions. They consist of complex reactions in which the specific rates of each reaction should be determined. They often occur in industrial processes. These reactions can be simple, elementary, irreversible and reversible, or even nonelementary. Some cases are ... 

Initially, let us define yield and selectivity for multiple reactions occurring simnl-taneously, for reactions in parallel, series, or mixed. When there is only one reaction step, the yield is confused with the conversion. 

There are many variations of the simple form of stirred-tank reactor just considered multiple units in parallel, series, split streams, more than one reaction, etc. Some of these will be discussed in Chap. 4. Deviations from the assumption of complete mixing are mentioned in Sec. 3-5 and discussed in more detail in Chap. 6.
