(Reactor selection and operating conditions) For each of the following sets
of reactions describe your reactor system and conditions to maximize the
desired product D. Make sketches where necessary to support your choices.
The rates are in (mol/dm - s). and concentrations are in (mol/dm').

() Consider the following parallel reactions?
(1)
-IA = 10 exp(-8,000 K/T)C,C,
A +B →D
(2)
A - U
-P2A = 26 exp(-10,800K/T)C,
(3)
U - A
-rsu = 10,000 exp(-15,000 K/T)C,
(g) For the following reactions (mol/dm/min)
-rIA = 800 e-k0 KTCa
-P2 = 10 e00 KinC,C,
-r3p = 10" e-k0 K"C,C
(1)
A +B →D
(2)
A +B - U
-300 K/T
(3)
D+B → U;
(1) What reactor and conditions would you choose to maximize Spu,u,?
(2) What temperature (300 K < T < 700 K) would you recommend
to maximize the overall selectivity for CAn = CBo =1 mol/dm and
Vo = 1 dm'/min?
