An endothermic second order reaction is carried out in an adiabatic plug flow reactor. The rate of heat generation is ___________________?
Correct answer: A. Maximum at the inlet of the reactor
- A. Maximum at the inlet of the reactor
- B. Maximum at the exit of the reactor
- C. Maximum at the centre of the reactor
- D. Constant throughout the reactor
Explanation
For an endothermic adiabatic reactor, the temperature falls as the reaction proceeds, while reactant concentration also decreases. Both effects reduce the rate, so the maximum rate occurs at the inlet.
