With increase in the order of reaction (for all positive reaction orders), the ratio of the volume of mixed reactor to the volume of plug flow reactor (for identical feed composition, flow rate and conversion)?
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remain same
- D. Increases linearly
Explanation
For a positive-order reaction, a mixed reactor evaluates the rate at the lowest concentration, the exit concentration, while a plug-flow reactor uses higher concentrations through much of its volume. Increasing the order magnifies this difference, so the mixed-to-plug-flow volume ratio increases.
