Constant molar flow rates were assumed in the treatment of this question, how would your approach to this problem differ if this assumption were not valid? Assuming that the given reaction is highly exothermic, what is the advantage of using a semi-batch reactor for this process?
These questions are of the Socratic form because they probes implications and consequences of changing the conditions of the original problem. The student is required to understand the problem in its entirety rather than just memorizing the approach used for specific conditions.
