Ch 22: Chemical Dynamics & Reaction Rates

About This Chapter

Understanding the chemistry dynamics and reaction rates is critical for basic chemistry knowledge. In this chapter, you can review solubility equilibrium and collision theory.

Chemical Dynamics & Reaction Rates- Chapter Summary

This chapter of video lessons will focus on different reaction rates that are seen in chemistry. The information within this chapter will help you understand how temperature and catalysts affect reactions. Goals that can be reached in this chapter include:

  • Understand what the solubility equilibrium is
  • Learn about the rate of chemical reactions
  • Explore the difference between endothermic and exothermic reactions
  • Explain the collision theory
  • Define reaction order
  • Comprehend the relationship between the reaction mechanism and reactions
  • Identify how temperature affects reactions
  • Review how catalysts can speed up a reaction

The video lessons use a timeline feature that makes it easy to watch and rewatch specific topic areas in any order you prefer. You'll find self-assessment quizzes that allow you to gauge your retention of lesson topics. The results of these quizzes are available immediately and provide a quick link back to the lesson topics you missed.

Solubility Equilibrium: Using a Solubility Constant (Ksp) in Calculations

1. Solubility Equilibrium: Using a Solubility Constant (Ksp) in Calculations

Learn the definition of solubility and solubility constant (Ksp) in this lesson. Interpret solubility constants and make calculations involving the dissociation of a slightly soluble compound given molar solubility.

Rate of a Chemical Reaction: Modifying Factors

2. 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.

Endothermic and Exothermic Reactions

3. Endothermic and Exothermic Reactions

Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.

Collision Theory: Definition & Significance

4. 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!

Rate Constant and Rate Laws

5. Rate Constant and Rate Laws

Learn what the rate law is and how the rate constant relates to it. Learn what reaction order is and how to determine reaction order when given experimental data containing concentration and reaction rate.

Reaction Mechanisms and The Rate Determining Step

6. 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.

Rate of a Chemical Reaction: Effect of Temperature

7. 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.

Effect of Catalysts on Rates of Reaction

8. Effect of Catalysts on Rates of Reaction

In this video lesson, we will learn how catalysts speed up chemical reactions. We'll also discuss how catalysts are used in industry and consider the catalysts in our own bodies. A short quiz will test your new knowledge.
