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

Rate of a Chemical Reaction: Modifying FactorsLearn about factors that can affect the rate of chemical reactions.
Rate Constant and Rate LawsGet a look at rate laws by using experimental data to determine reaction rate constants.
Rate of a Chemical Reaction: Effect of TemperatureUnderstand how temperature can affect the rate of reaction in a chemical experiment.
Collision TheoryExplore this theory, based on particle concentration, that explains why reaction rates are different for various reactions.
Activation Energy and CatalystsExamine the amount of energy needed for a reaction to start and how catalysts can change this.
Reaction Mechanisms and The Rate-Determining StepLook at some reactions to see which step determines the overall rate of the reaction.
Kinetics and EquilibriumDiscover the relationship between rate constants for forward and reverse reactions and how to find the equilibrium constant.
