C$)$ Identify the reactor configuration, flow pattern and volume of individual reactors in the flow model if the total reactor volume is $5m^3.$

Problem $4(10$ points$)$:

Consider an ideal CSTR with mean residence time $\frac{?}{\text{b}\text{a}\text{r}}(t)$ with volume $V$ and volumetric flow rate $F.$

A$)$ At a steady state operation of CSTR$,$ a tracer impulse of M moles is injected into the system at time $t$ equals $0,$ as shown in Figure $6.$ Derive the expression accounting for the tracer concentration at the outlet of the CSTR at time $t$ in terms of $t\frac{,}{b}ar(t),V,F,$ and $M.$
