About This Chapter

Chemical kinetics include the ideas surrounding chemical reactions. This chapter in the Praxis II General Science course reviews the material on kinetics that will be appearing on the exam.

Praxis II General Science: Chemical Kinetics - Chapter Summary

Chemical kinetics makes up an essential area of chemistry and the physical sciences. This portion of the video lessons in the Praxis II General Science course acts as a review for your upcoming exam, providing you with an entertaining and easy-to-follow study guide that you can browse at your own pace. The topics included in this chapter are as follows:

  • Modifying factors and effects of temperature in reactions
  • The significance of collision theory
  • Activation energy
  • Reaction mechanisms
  • Reaction rate constant and equilibrium constant

These video lessons all come equipped with a timeline feature that allows you to conveniently skip ahead or jump back in the presentation if you need to go over a certain area again or you wish to review the lesson in another order. Furthermore, since the lessons are optimized for mobile devices, you can resume your studies while on the go once you leave your computer.

Praxis II General Science: Chemical Kinetics Objectives

The Praxis II General Science exam is administered to teachers of varying grade levels in differing states for certification in science classes. The questions about chemical kinetics will appear in the Physical Science section of the exam, which takes up approximately thirty-eight percent of the test and will be entirely in multiple-choice format.

Rate of a Chemical Reaction: Modifying Factors

1. Rate of a Chemical Reaction: Modifying Factors

Why are some reactions much faster than others? Is it possible to change how fast a reaction occurs? In this lesson, you will learn what the rate of a chemical reaction is. You will also discover how factors such as temperature, concentration, surface area, and catalysts impact reaction rates.

Rate of a Chemical Reaction: Effect of Temperature

2. Rate of a Chemical Reaction: Effect of Temperature

Learn how temperature affects reaction rates. Discover the rate law as well as how the Arrhenius equation relates to the rate law and predicts the effect of temperature on the rate of reaction.

Collision Theory: Definition & Significance

3. Collision Theory: Definition & Significance

This lesson will define and explain collision theory and explore how it is related to chemical reactions and reaction rates. So if you've ever wondered how two particles combine to form a new product, read on!

Activation Energy and Catalysts

4. Activation Energy and Catalysts

Learn how to define activation energy and how it relates to a reaction's energy. Learn what an activated complex is and where it fits into an activation energy diagram. Discover how a catalyst works to change the activation energy of a reaction and what this means to metabolism in the body.

Reaction Mechanisms and The Rate Determining Step

5. Reaction Mechanisms and The Rate Determining Step

This lesson explores what a reaction mechanism is and how it relates to the speed of a reaction. You'll discover how to pinpoint the rate-determining step and learn how to write a rate law based on the rate-determining step.

Chemical Kinetics, Reaction Rate Constant & Equilibrium Constant

6. Chemical Kinetics, Reaction Rate Constant & Equilibrium Constant

Are formulas, rate constants, and chemical reactions getting you down? Don't worry, this lesson will explain how reaction rate and equilibrium constants are related to chemical reactions.
