Question 1

in a reaction A→R→S, which type of reactor gives the maximum amount of R? (PFR or MFR)

Answer 1

PFR

Question 2

in a reaction A→R→S in a PFR, when the maximum concentration of __ is reached, that is also the point where the rate of formation of ___ is at it’s most rapid.

Answer 2

R, S.

Question 3

True or false, MFR feed is always pure A, no R nor S reactant which means CRo and CSo are zero in the feed.

Answer 3

True

Question 4

true or false, in a reaction A→R→S in a pfr, as A reacts into R, and R reacts into S all happening successively , if k1 and k2 are equal, there will be no optimum time so you will resort to looking at the graph for CR max.

Answer 4

True
