Recall that the CSTR is modeled as being well mixed such that there are no spatial variations in the reactor. For the general reaction,
the CSTR mole balance Equation (1-7) can be arranged to
We now substitute for FA in terms of FA0 and X
and then substitute Equation (2-12) into (2-11)
Simplifying, we see that the CSTR volume necessary to achieve a specified conversion ...
