Q$5)$ You are designing a reactor for a liquid$-$phase process in which an inlet stream of $100$

$mo\frac{l}{m}in$ of pure reactant $A(C_{A0}=20\frac{\text{m}\text{o}\text{l}}{L})$ is to be converted to product $B$ in an irreversible

elementary reaction: $AB.$

a$.$ What size PFR is necessary to achieve $60\%$ conversion if the reactor is operated

isothermally at $500K?($Answer: $9\mathrm{.}165$ L$).$

b$.$ Your customer decides that they would rather use an adiabatic CSTR than the isothermal

PFR from part a$.$ If the target is still $60\%$ conversion, what size CSTR is needed if the

reactor feed is held at $500K?($Answer: $1\mathrm{.}13$L$).$

Data:

$K(T=500K)=0\mathrm{.}5mi{n}^{-1}$

$Ea=65k\frac{J}{m}ol$

$H_{rxn}(500K)=-10k\frac{J}{m}ol$

$C_{p,A}=C_{p,B}=60\frac{J}{m}$olK $($There solution for part a in chegg want to solution for part b$)$
