P$8-7{?}_C($Reactor selection and operating conditions$)$ For each of the following sets of reactions, describe your reactor system and conditions to maximize the selectivity to D$.$ Make sketches where necessary to support your choices. The rates are in $(mo\frac{l}{d}{m}^3*s),$ and concentrations are in $(mo\frac{l}{d}{m}^3).$
