$9\mathrm{.}4.$ We plan to run the reaction of Example $)=4\frac{\text{m}\text{o}\text{l}}{l}$iter,$F_{Ao}=(1000\frac{\text{m}\text{o}\text{l}}{m}in$ in a plug flow reactor kept at $40C$ throughout to $90\%$ conversion. Find the volume of reactor needed.

$9\mathrm{.}5.$ Redo Example $9\mathrm{.}4$

$9\mathrm{.}6.$ Redo Example $9\mathrm{.}5$ where $C_{A0}=4mo\frac{l}{?}$ liter is replaced by $C_{A0}=1$

mol $9\mathrm{.}7.$ Rer, and Example $9\mathrm{.}6$

$9\mathrm{.}7.$ Redo Example $9\mathrm{.}6$

$9\mathrm{.}8.$ Redo Example $9\mathrm{.}7$

where $F_{A0}$ remains unchanged at $1000$mol$\frac{A}{m}in.$

$9\mathrm{.}9.$ We wish to run the reaction of Example $9\mathrm{.}4$ in a mixed flow reactor to $95\%$ conversion for a feed concentration $C_{AO}=10mo\frac{l}{l}$iter and feed rate of $v=100$ liter $\frac{?}{\text{m}\text{i}\text{n}}.$ What size of reactor would we need?
