Kinetics

If a chemical reaction is too slow, it may not be practical. If it’s too fast, however, it may be dangerous! Studying reaction rates helps us make things economically and safely. It also helps us understand on a molecular level how and why chemical reactions take place.


Introduction to Reaction Rates

Kinetics is the study of the rates of chemical reactions. How can the rate of a chemical reaction be measured? What factors will influence or change the rate of a chemical reaction?
