Five CSTRs of equal volumes of $10d{m}^3$ are available to be connected in series. A first

order reaction takes place in the reactors.

a$.$ For an overall conversion of $99\%$ what is the Damkohler number $($Da$)$ for this set$-$

up$?$

b$.$ If the rate constant is $\frac{0\mathrm{.}251}{s},$ what is the volumetric flow rate of the feed?
