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/dm³s, and the concentrations are in mol/dm³. No single correct answer for the best reactor scheme. First specify what conditions are ideal (e.g., low C_A, high C_B, high T), then think of a reactor setup that would create those conditions.

1) A + B D -r_1A = 10exp(-8,000 K/T)C_AC_B

2) A + B U -r_2A = 100exp(-1000 K/T)C_A^1/2C_B^3/2

1) A D -r_1A = 4280exp(-12,000 K/T)C_A

2) D U₁ -r_2D = 10,100exp(-15,000 K/T)C_D

3) A U₂ -r_3A = 26exp(-18,800 K/T)C_A

1) A + B D -r_1A = 10⁹exp(-10,000 K/T)C_AC_B

2) D A + B -r_2D = 20exp(-2000 K/T)C_D

3) A + B U -r_3A = 10³exp(-3,000 K/T)C_AC_B
