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 $($mol$/$L$.$s$),$ and concentrations are

in $($mol$/$L$).($a$)(1),A+BD,-r_{1A}=10$exp$(-8,000\frac{K}{T})C_A{C}_B$
