We believe there is far too much material in the textbook to attempt to cover in one semester or two quarters. The princpiles assignment schedules therefore cover only Chaptersand within those chapters some topics are omitted e. We will discuss the case studies in Chapters separately.

The bonus problems may be assigned as individual exercises or students may work on them in pairs. We have had good experience with the latter approach.
Creativity Exercises The creativity exercises in the text are designed to stimulate divergent thinking and to induce the students to think about course material from different perspectives. We have used such exercises both as extra-credit assignments to individuals or pairs of students or as the foci of in-class brainstorming sessions. In all cases, we have found that they invariably lead to innovative, clever, and often amusing ideas; they give students who are by nature creative an opportunity to demonstrate their talent and they help other students develop creative problem-solving skills; and the students usually enjoy doing them.
However, to provide an idea of the kind of things that students come up with, we have included on pp. Xhemical Masters Several of our colleagues have suggested that we include in the text enlarged versions of some of the figures, such as the psychometric charts, which are difficult to read in reduced format.
We have chosen not to do so, since whether they are inserts or fold-outs such charts tend to be ripped off one way or another or otherwise lost. Instead, we have included in this manual, beginning on p.
These masters can be used to make transparencies for lectures; they can also be copied and distributed to the students for use in solving problem. Case Studies The case studies comprise Chapters 12 through 14 of the text.
In them, we seek to 1 illustrate the development of complex chemical processes from basic principles, and to provide a broad process context for the text material; 2 raise questions that require students to think about topics strictly beyond the scope of the first course, and to seek out sources of information other than the text; 3 accustom the students to team project work. We do not organize the activities of case study v teams, nor do we assign team leaders, although we suggest to the students that they do so.
This is a risk, and sometimes it is necessary to step in and get a laggard group started. However, letting the teams shape their own working relationships and structure their own activities usually is an enlightening experience to the students. Problem Solutions The detailed solutions to of the chapter-end problems constitute the principal content of this manual.

The solution to the last problem of Chapter 10 is left as an exercise for the professor, or for anyone else who wants to do it. With few exceptions, the conversion factors and physical property data needed to solve the end- of-chapter problems are contained in the text. It may be presumed that conversion factors for which sources are not explicitly cited come from the front cover table; densities, latent heats, and critical constants come from Table B.
As the reader of the text may procesees discovered, we believe strongly in the systematic use of the flow charts in the solution of material and energy balance problems.
When a student comes to us to ask for help with a problem, we first ask to see the labeled flow chart: Other instructors we know demand fully labeled flow charts and solution outlines at the beginning of every problem solution, before any calculations are performed. In any case, we find that the students who can be persuaded to adopt this approach generally complete their assignments in reasonable periods of time and do well in the course; most of those who continue to resist it find themselves taking hours to do the homework problems, and do poorly in the course.
An Impassioned Plea It is common practice for instructors to photocopy solutions from the manual and to post them after the assignments are handed in, or, even worse, to distribute the solutions to the students.
What happens then, of course, is that the solutions get into circulation and reincarnate with increasing frequency as student solutions. After one or two course offerings, the homework problems consequently lose much of their instructional value and become more exercises in stenography than engineering problem solving.
In the stoichiometry course particularly, the concepts are relatively elementary: A great deal of classroom lecturing on concepts should therefore not be necessary, and a good deal of the class time can be spent in outlining problem solutions.
