For series reaction, the relative yield__________________?
Correct answer: D. Both A. and C. hold good
- A. Is always greater for plug-flow reactor than for the single CSTR of the same volume
- B. Statement in A. is wrong
- C. Decreases with increasing conversion
- D. Both A. and C. hold good
Explanation
For a consecutive reaction in which an intermediate is the desired product, its relative yield generally falls as conversion increases because the intermediate has more opportunity to undergo the secondary reaction. A PFR generally gives a higher intermediate yield than one CSTR of the same volume, so both statements apply.
