Part 2 of a 2-part series developed to assist high school students understand chemistry, this text can be used in conjunction with other textbooks or as a standalone textbook. Part 2 focuses on reactions, kinetics, and thermodynamics. Depending on the pace and coverage of the material, this is usually the second year of an in-depth look of chemistry or the second semester if used as a brief review. I use this text as a supplement for the AP Chemistry Class.
