1. complete mixed flow reactor (cmfr) and plug-flow reactor (pfr) are two extreme of ideal reactor models. which of the following statement on cmfr and pfr is not true? (2 pts) a. for each plug inside a plug-flow reactor, there is no mass exchange along the axial direction (the direction of the flow). b. the plug flow reactor is to model ideal pipe flow. c. the plug flow reactor can be treated as a moving batch reactor. d. for the same initial concentration, hydraulic detention time, and first-order decay rate constant, effluent concentration from a plug flow reactor is higher than that from a complete mixed flow reactor.
