Problem $2(30$ points$).$ You observe the following outlet tracer signals from reactors that should

have an actual volume of $100L$ and inlet flow rates of $1\frac{L}{m}in$ with $C_{A0}=1\mathrm{.}0M.$ Area refers to

the area of relevant peaks, and the graphs are unnormalized concentration profiles vs$.$ time.

a$)$ For these two reactors:

i$.$ Identify a model for computing the effective volume of each reactor based on the

ones discussed in class $($e$.$g$.,$ PFR with recycle, CSTR and PFR in series, reduced

or larger volume CSTR$,$ PFRs in parallel, etc$)$;

ii$.,$ What is the total effective volume? Is this more or less than you expected?

iii. What, if any, are the non$-$idealities, e$.$g$.,$ dead volume or more volume than

expected, channeling, PFR$-$like conversion in a CSTR$,$ and$/$or bypass in the reactor?

b$)$ For a liquid phase, first order reaction with $k=0\mathrm{.}05mi{n}^{-1},$ what is the conversion for each

reactor?
