basis for predicting the effect of a concentration change of a reactant on the
overall rate of reaction. Another way of determining the effect of concentration
changes is actual experimentation.
CHAPTER SUMMARY
The following terms summarize all the concepts and ideas that were introduced in
this chapter. You should be able to explain their meaning and how you would use
them in chemistry. They appear in boldface type in this chapter to draw your
attention to them. The boldface type also makes it easier for you to look them up if
you need to. You could also use the Internet search engine google.com on your
computer to get a quick and expanded explanation of these terms, laws, and
formulas.
