Multiple Reactions and Selectivity: ConcepTest and Example Problem
Try to answer this ConcepTest and solve this example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. By the end of this module, you should be able to answer these on your own. Answers will be given later in this module.
Example Problem 1
The reaction A + B → 2D is accompanied by an undesired side reaction where A + B → U1 + U2. Expressions for the rates of the desired and undesired reactions are given below. If the reaction is run at 70% conversion, would you expect the selectivity toward the desired product to be higher in a PFR or in a CSTR?
