#$2$: Same reaction $($CSTR$)$ now is carried out in a PFR$.$ Species A enters the reactor at a molar

flow rate of $F_{A0}=0\mathrm{.}4mo\frac{l}{s}.$ Using the same data presented in #$1$ i$)$ calculate the volume necessary

to achieve $80\%$ conversion in a PFR; ii$)$ shade the area in the Levenspiel plot that would give the

PFR volume necessary to achieve $80\%$ conversion.
