A first order reaction requires two unequal sized CSTR. Which of the following gives higher yield ?
Correct answer: D. Either of the arrangement A. or B. will give the same yield
- A. Large reactor followed by smaller one
- B. Smaller reactor followed by larger one
- C. Data insufficient, can't be predicted
- D. Either of the arrangement A. or B. will give the same yield
Explanation
For a first-order reaction in CSTRs, the overall conversion depends on the sum of the reactor volumes divided by the flow rate, not on their order. Interchanging the two unequal reactors therefore gives the same yield.
