With the same reaction time, initial concentration and feed rate, the reaction 2A → B is carried out separately in CSTR and P.F. reactor of equal volumes. The conversion will be__________________?
Correct answer: C. Higher in P.F. reactor
- A. Same in both the reactors
- B. Higher in CSTR
- C. Higher in P.F. reactor
- D. Data insufficient; can't be predicted
Explanation
For a normal positive-order reaction, the plug-flow reactor maintains a higher reactant concentration over much of its length than the CSTR, giving a higher average rate. Therefore, at equal volume, the plug-flow reactor gives greater conversion.
