The liquid$-$phase reaction

A$+$B C

$->$

follows an elementary rate law and is carried out isothermally in a flow

system. The concentrations of the A and B feed streams are $2$ M before

mixing. The volumetric flow rate of each stream is $5$ dm$3/$min$,$ and the

entering temperature is $300$ K$.$ The streams are mixed immediately before

entering. Two reactors are available: One is a $200$ dm$3$ CSTR that can be

operated at $77$oC$,$ and the other is an $800$ dm$3$ PFR operated at constant

temperature of $300$ K$.$ Note that k $=0\mathrm{.}07$ dm$3/$mol$$min at $300$ K and E $=$

$20$ kcal$/$mol$.(40$ Points$)$

What conversion would be obtained if the CSTR and PFR were

operated at $300$ K and connected in series? In parallel with $5$ mol$/$min

to each? Which configuration would you prefer to choose and why?
