Ch 16: Rate & Extent of Chemical Changes

About This Chapter

In these lessons and quizzes, you'll learn more about the extent and rate of change in chemical reactions. You can use this chapter to prepare and test yourself for an examination or homework assignment.

Rate & Extent of Chemical Changes - Chapter Summary

In this chapter, you will learn how to calculate the rates of chemical reactions and how to analyze and interpret reaction rate graphs. In your lesson review, you will discover that the rate of a chemical reaction can be impacted by different factors. The concept of collision theory will also be introduced along with its relationship to reaction rates.

The concept of activation energy will be discussed, as well as how it affects metabolism in the body. You will receive examples of reversible chemical reactions along with definitions of the phenomenon. The chapter is completed with LeChatelier's Principle and how it relates to equilibrium. After you have reviewed the lessons in this chapter, you should be able to:

  • Point out which factors impact chemical reaction rates
  • Understand how two particles combine to form something new
  • Place an activated complex into an activation energy diagram
  • Identify examples of reverse chemical reactions
  • Define LeChatelier's Principle
  • Explain the factors that disrupt equilibrium

Calculating Rates of Reaction: Formula, Graphs & Examples

1. Calculating Rates of Reaction: Formula, Graphs & Examples

In this lesson we will describe how to monitor a chemical reaction's progress, by describing the rate of chemical reaction. We will also interpret plots of chemical reactant and product amounts versus time in order to calculate the reaction rate.

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.

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.

Reversible Chemical Reactions: Definition & Examples

5. 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.

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

6. 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.

Factors that Affect Chemical Equilibrium

7. Factors that Affect Chemical Equilibrium

In this lesson, you will learn how varying the conditions of concentration, temperature, and pressure will affect the reactants and products in a chemical reaction at equilibrium.
