Ch 12: MTLE Chemistry: Chemical Reactions

About This Chapter

Learn about chemical reactions in this chapter of the MTLE Chemistry exam study guide. Video lessons and self-assessment quizzes teach you all you need to know about chemistry in preparation for the test.

MTLE Chemistry: Chemical Reactions - Chapter Summary

Lessons in this chapter explore common chemical reactions, writing and balancing combustion reactions, and decomposition reactions. Precipitation reactions and the rate law are also discussed. Additionally, by the end of this chapter, you should be all set to take on any MTLE Chemistry test items about:

  • Factors that affect reaction rates
  • Collision theory
  • Activation energy
  • The rate-determining step
  • Chemical kinetics

Knowledgeable instructors thoroughly explain each topic through short, engaging video lessons. Self-assessment quizzes can be used to test your knowledge, and you can print them as worksheets if you ever have to study offline. The jump feature under the Timeline tab allows you to skip directly to main points within the video lessons.

Common Chemical Reactions and Energy Change

1. Common Chemical Reactions and Energy Change

This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.

Writing and Balancing Combustion Reactions

2. Writing and Balancing Combustion Reactions

Discover what a combustion reaction is as well as what reactants are needed and what products are produced. Learn to write and balance a combustion reaction. Through the concepts of bond energies, learn how to explain why combustion reactions are largely exothermic.

Decomposition and Synthesis Reactions

3. Decomposition and Synthesis Reactions

Learn how to write, identify and predict the products of simple synthesis and decomposition reactions. This includes the composition of reactions with oxygen, of two metals, and of metals with nonmetals, as well as the decomposition of metal carbonates, metal chlorates and metal hydroxides.

Precipitation Reactions: Predicting Precipitates and Net Ionic Equations

4. Precipitation Reactions: Predicting Precipitates and Net Ionic Equations

Learn what a precipitate is and predict when it will form in an aqueous chemical reaction, usually a double-replacement reaction. Learn what an ionic equation is, how it differs from a net ionic equation and how to write a net ionic equation.

Rate of a Chemical Reaction: Modifying Factors

5. 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 Constant and Rate Laws

6. 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.

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.

Collision Theory: Definition & Significance

8. 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

9. 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

10. 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

11. 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.
