Chapter 16: Reaction Rates
... Expressing Reaction Rates In the Launch Lab, you discovered that the decomposition of hydrogen peroxide can be a fast reaction, or it can be a slow one. However, fast and slow are inexact terms. Chemists, engineers, chefs, welders, concrete mixers, and others often need to be more specific. For exam ...
