A first order reaction is to be treated in a series of two mixed reactors. The total volume of the two reactors is minimum, when the reactors are_____________________?
Correct answer: A. Equal in size
- A. Equal in size
- B. Of different sizes
- C. Of such size that the ratio of their volumes is < 5
- D. None of these
Explanation
For two CSTRs carrying out a first-order reaction, minimizing total volume requires equal concentration-ratio reductions in the two reactors. This gives equal reactor volumes, unlike a single large CSTR followed by a small one.
