The most unsuitable reactor for carrying out reactions in which high reactant concentration favours high yields is________________________?
Correct answer: C. Backmix reactor
- A. Series of CSTR
- B. Plug flow reactor
- C. Backmix reactor
- D. PFR in series
Explanation
When high reactant concentration improves yield, backmixing is undesirable because a CSTR operates throughout at the lower exit concentration. A plug-flow reactor maintains higher concentration near the inlet, so the backmix reactor is most unsuitable.
