2. For the reaction aA + bB  rR, with inerts iI, Figs. 4.4 and 4.5 show the symbols
commonly used to tell what is happening in the batch and flow reactors. These
figures show that there are two related measures of the extent of reaction, the
concentration CA and the conversion XA. However, the relationship between CA
and XA is often not obvious but depends on a number of factors. This leads to three
special cases, as follows.
Xa means conversion of reactant ‘a’, its max value is ‘1’ when ‘a’ is totally consumed
(reaction is completed) and minimum value is ‘0’ when reactant is just added and
reaction hasn’t started.
 Constant Density Batch and Flow Systems.
This includes most liquid reactions and also those gas reactions run at constant
temperature and density. Here CA and XA are related as follows:

6.  Case 3 can be distinguished from other cases but case 1 and 2 aren’t
distinguishable unless mentioned.
 As a rule of thumb if value of zeta is ‘0’ we use case 1 and for non-zero zeta value
we use case 2.
