In class we demonstrated the difference between conversion obtained by $2$ CSTRs in series and $2$

identical CSTRs in parallel, where the feed is split equally between the parallel reactors. Consider the

analogous situation of $3$ CSTRs in series or parallel where the feed would be split equally into $3$ streams.

Consider the same first$-$order rate law from the notes, $-r_A=k{C}_A.$ What is the difference in conversion

achieved by the reactors in series as compared to the reactors in parallel?
