The following irreversible first-order reaction occurs at constant density

ABC where : k₁ = 0.12/min and k₂ = 0.07/min

This reaction system is to be analyzed in continuous flow reactors with a volumetric feed rate of 5 ft³/min and the feed

composition is C_AO = 0.12 mole/ft³ and C_BO = C_CO = 0.

a) What size of backmix reactor will maximize the yield of B and what is the maximum concentration of B in the effluent

stream?

b) For a higher production rate of B, which of the following reactors is preferable? Validate your answer.

b.1 single stirred tank of volume 12 ft³

b.2 two stireed tanks in series, each with a volume of 8 ft³

b.3 a plug flow reactor with a volume of 11 ft³
