Ch 18: Prentice Hall Chemistry Chapter 18: Reaction Rates and Equilibrium

About This Chapter

The Reaction Rates and Equilibrium chapter of this Prentice Hall Chemistry Companion Course helps students learn the essential lessons associated with reaction rates and equilibrium. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Reaction Rates and Equilibrium textbook chapter.

How It Works:

  • Identify the lessons in the Prentice Hall Reaction Rates and Equilibrium chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the reaction rates and equilibrium topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Chemical and dynamic equilibrium
  • What LeChatelier's principle is
  • Equilibrium constant and reaction quotient
  • Ways to calculate solubility equilibrium using a solubility constant
  • The second law of thermodynamics
  • The requirements of free energy and matter in living systems
  • How Gibbs free energy is helpful
  • What the rate constant and rate law are
  • Factors that affect the rate of a chemical reaction

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.

Reversible Chemical Reactions: Definition & Examples

2. Reversible Chemical Reactions: Definition & Examples

Chemical reactions don't just go forwards; sometimes, they can go backwards. Learn what a reversible chemical reaction is, and see some examples of such reactions.

Equilibrium: Chemical and Dynamic

3. Equilibrium: Chemical and Dynamic

Learn the definition of chemical equilibrium and how it is dynamic. Discover what the equilibrium constant is and how it shows whether the reaction favors the reactants or products. Learn how chemists designate equilibrium in an equation and how they show the difference in reaction rate.

LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

4. LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

Learn how Le Chatelier's Principle describes the disruption and re-establishment of equilibrium. Learn to explain the factors that disrupt equilibrium, such as concentration, temperature, and pressure. Learn how each of these factors affects a system in equilibrium.

Equilibrium Constant (K) and Reaction Quotient (Q)

5. Equilibrium Constant (K) and Reaction Quotient (Q)

In this lesson, we will first define and explain the notion of a chemical equilibrium. Then, you'll learn about the equilibrium constant and reaction quotient. Finally, we'll round off the lesson with a couple of examples to solidify what you've learned!

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

6. 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.

Second Law of Thermodynamics: Entropy and Systems

7. Second Law of Thermodynamics: Entropy and Systems

In this lesson, we'll learn about the second law of thermodynamics. By studying this law, you'll understand how energy works and why we're all moving towards eventual chaos and disorder.

Living Systems Requirement for Free Energy and Matter

8. Living Systems Requirement for Free Energy and Matter

Free energy and matter are required by all living things in order to grow, reproduce, and maintain biological processes. Additionally, free energy and matter must also be recycled through the environment in order to remove dead material and allow for new growth.

Rate Constant and Rate Laws

9. 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.
