When the density of the reaction mixture is constant in a chemical reaction, the ratio of the mean residence time to space time is__________________?
Correct answer: C. 1
- A. > 1
- B. < 1
- C. 1
- D. 0
Explanation
With constant density, the volumetric flow rate does not change through the reactor, so space time V divided by flow rate equals the mean residence time. Their ratio is therefore one.
