a. For an SO2 flow rate of 100 lbmol/hr, determine the volume of the CSTR required to achieve the specified 70% conversion. The rate of reaction is described by Preaction,butadiene krCbutadieneCSO2 where k, = 4.44ft° /lbmol hr. b. Would the addition of an inert (non-reacting) liquid to the butadiene feed increase the required reactor size, or decrease it? Why?

Question
Butadiene sulfone (MW=118) can be produced by the fol-
lowing irreversible liquid-phase reaction at 190° F and 160 psia:
7.
Butadiene + SO2
Butadiene Sufone
Pure SO2 is fed to the reactor in one stream. Pure butadiene
(MW=54) is fed separately into the reactor at a molar flow rate
that is 25% more than that required to react with all of the SO2,
and 70% of the entering butadiene is converted into product.
The density of the stream leaving the reactor is 42.2 lbm/ft³.
