For a system with two entering reactant streams,earliness or lateness of mixing can be very important. A 60 B LWell mixed at entry, Separate parallel LMixing only occurs so A and B have flows so A and B at exit leaving no lots of time for reaction are unable to react time for reaction Figure 11.5 Early or late mixing affects reactor behavior. 77 • For a system with two entering reactant streams, earliness or lateness of mixing can be very important
