Unformatted text preview: 14-0A Workbook for Chemical Reaction Equilibria© J.R. Elliott and Carl T. Lira 1/12/02The motivation for this project derives from Paper 59c at the AIChE Meeting in Los Angeles, November,2000, by V.A. Burrows and G.B. Raupp. The concept is to provide a self-contained tutorial supplement to theElliott-Lira textbook similar in format to the kinds of workbooks that should be familiar from K-12 education.Basically, the material should be presented in whatever manner makes the students feel most comfortable. Theimportant thing is that they learn the material.The intent is to briefly supplement the discussion in the text, then provide example problems to illustrate ingreat detail how a particular analysis is performed. Exercise problems immediately following each example aredesigned to look very similar to the example, instantly reinforcing the principles covered in the example. Thedisadvantage of this approach is that it discourages the independent thought and analysis process that engineersmust ultimately develop. Note, however, that this is a supplement to the existing text. The existing homeworkproblems remain as general statements like homework problems in any text.Clearly there is more work involved for students who pursue the workbook. There is nothing wrong with thatif the workbook provides a path for students to learn the material who might not have learned it otherwise. Hence,we suggest that the workbook not be a required element for all students, but completion of the workbook might gainrecognition in a small component of the overall grading such as “class participation.” Long term, it would be veryinteresting to study how student success correlates with completion of the workbook. We would expect asignificant correlation that might depend on the interaction between overall grade in the course and completion ofthe workbook.The specific chapter covered by this particular workbook is Chapter 14, Reacting Systems. More than anyother chapter, we have heard suggestions that the coverage in this chapter is quite broad, with insufficient examplesto thoroughly grasp the principles. Addressing this concern is quite fitting within the workbook context sinceproviding examples is what the workbook is all about. Note that we have included complete solutions to thepractice problems stated in the text in addition to the additional workbook examples. With these completesolutions, combined with the additional workbook examples, the total number of solved examples is roughly tripled.We hope that these additions will help to relieve the difficulty perceived by students with this subject matter.14-1A Workbook for Chemical Reaction Equilibria14Reacting Systems......................................................................................................................................... 14-214.1Reaction Coordinate ................................................................................................................................ 14-214.1.114....
