Ch 12: AP Chemistry: Kinetics

About This Chapter

Watch chemical kinetics video lessons and learn about reaction rates, activation energy, collision theory, and more. These lessons are just a portion of our AP Chemistry course.

AP Chemistry: Kinetics - Chapter Summary and Learning Objectives

Chemical kinetics is the study of the rates of chemical processes and what factors determine those rates. In this chapter, our instructors will show you how fast chemical reactions happen and explain various theories as to why. You'll learn about rate laws, determining rate constants, and calculating activation energy. Each lesson focuses on a different aspect of kinetics, from catalysts to collision theory. After completing this chapter, you should be able to:

  • Determine the rate constants for various reactions
  • Understand why reactions happen at certain rates
  • Find the rate-determining step in a reaction
  • Explain how various factors can affect reaction rates
