An exothermic reaction takes place in an adiabatic reactor. The product temperature ______________ reactor feed temperature?
Correct answer: B. Is always greater than
- A. Is always equal to
- B. Is always greater than
- C. Is always less than
- D. May be greater or less than
Explanation
In an adiabatic exothermic reactor, the heat released by reaction raises the sensible enthalpy of the reacting mixture, so the outlet temperature increases above the feed temperature. This assumes a nonzero extent of reaction and the usual constant-pressure or constant-volume reactor model.
