Chapter 18: Models for Nonideal Reactors

Additional Homework Problems

CDP18-BB

  You have a nonideal batch tank reactor, and your predecessor (who was promoted for his brilliance at modeling reactors) modeled it as two well-mixed batch reactors with transfer between them

Figure CDP14-B.
     
     
    You wish to check this model. Your predecessor stated that image 14eq65a.gif was 30 ft3 and image 14eq65.gif was 10 ft 3s. The transfer rate image was 0.1 ft 3 /s. At time t = 0, you put 0.1 lb mol of tracer into the region near the agitator (reactor I). If your predecessor was correct, what should be the concentration of tracer in reactor 100 s after you put in the tracer?
