The subscript to each of the problem numbers indicates the level of difficulty: A, least difficult; D, most difficult.

In each of the following questions and problems, rather than just drawing a box around Problems your answer, Write a sentence or two describing how you solved the problem, the assumptions you made, the reasonableness of your answer, what you learned, and any other facts that you want to include. You may wish to refer to W. Strunk and E. B. White, The Elements of Style, 4th ed. (New York: Macmillan, 2000) and Joseph M. Williams, Style: Ten Lessons in Clarity c£ Grace, 6th ed. (Glenview, 111.: Scott, Fores-man, 1999) to enhance the quality of your sentences. See (the Preface for additional generic parts (x), (y), (z) to the home problems.

Read through all the problems at the end of this chapter. Make up and solve an original problem based on the material in this chapter, (a) Use real data and reactions, (b) Make up a reaction and data, (c) Use an example from everyday life (e.g., making toast or cooking spaghetti). In preparing your original problem, first list the principles you want to get across and why the problem is important. Ask yourself how your example will be different from those in the text or lecture. Other things for you to consider when choosing a problem are relevance, interest, impact of the solution, time required to obtain a solution, and degree of difficulty. Look through some of the journals for data or to get some ideas for industrially important reactions or for novel applications of reaction engineering principles (the environment, food processing, etc.). At the end of the problem and solution describe the creative process used to generate the idea for the problem, (d) Write a question based on the material in this chapter that requires critical thinking. Explain why your question requires critical thinking. [Hint: See Preface, Section B.2] (e) Listen to the audios on the CD  Lecture Notes, pick one, and describe how you might explain it differently.
