For the following set of reactions, describe a reactor system and the conditions to maximize

selectivity with respect to $D.$ Construct diagrams if necessary to support your choice. The

velocities are given in $(mo\frac{l}{d}m?.s$ and the concentrations in $(mo\frac{l}{d}m3$

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

$A+BU,-r_{2A}=100$exp$(-1,000\frac{K}{T})C_A^{\frac{1}{2}}{C}_B^{\frac{3}{2}}$
