Write a question based on the material in this chapter that requires critical thinking. Explain why your question requires critical thinking.

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 from the literature. (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)
