Rate of Chemical Reactions
Learning Time: 5-15 hours
Content: Rate of chemical reactions is the study of how fast reactions occur and the factors that affect this rate. This area covers the definition of reaction rate, rate law, collision theory, activation energy, catalytic effect, and enzyme acceleration. The TYT focuses on basic rate factors, while the AYT focuses on kinetic models and mechanisms. The current 2025 curriculum also covers catalytic conversion and environmental chemistry. Learning this topic forms the basis for reaction control and optimization.
