Packet B: Bonus 16

This condition names a type of chemical reactor that is characterized by parabolic velocity profiles as particles travel in parallel. For 10 points each:
[10e] What condition, largely absent in plug-flow reactions, involves minimal mixing and is contrasted with turbulent flow?
ANSWER: laminar flow [or laminar flow reactor; accept laminar regime; accept streamline flow]
[10h] For LFRs, this quantity’s namesake distribution is equal to tau squared over two times this quantity cubed and is generally a broad peak. Dye tracers are usually “pulsed” into reactors to determine this quantity.
ANSWER: residence time [or mean residence time; accept residence time distribution or RTD; accept transit time; accept retention time; accept space time; accept E(t); accept exit stage distribution; accept age distribution; prompt on time or t]
[10m] LFRs are useful for determining this other quantity using mean residence time, concentration, and the first Damköhler number. For a first-order reaction, this quantity is equal to the natural log of two divided by half-life.
ANSWER: reaction rate constant [or reaction rate coefficient; prompt on k; reject “rate”]
