A first order reaction requires two equal sized CSTR. The conversion is____________________?
Correct answer: B. More when they are connected in series
- A. Less when they are connected in series
- B. More when they are connected in series
- C. More when they are connected in parallel
- D. Same whether they are connected in series or in parallel
Explanation
For a first-order reaction, equal CSTRs in series give successive concentration reductions, producing a higher overall conversion than parallel operation. Parallel reactors effectively behave like one reactor of the same total volume when the feed is equally divided.
