Ch 44: Thermodynamics & Chemistry

About This Chapter

Go through this chapter to get a better handle on thermodynamics and chemistry. Although we provide you with extensive study aids, lesson materials, and other learning tools, we know that you may have questions, so we our instructors are available for you to consult if you need further assistance.

Thermodynamics & Chemistry - Chapter Summary

If you are feeling a little fuzzy about the details of thermodynamics and chemistry, this chapter can help you get back up to speed. Our instructors have designed these materials for learners of all levels. In other words, these lessons can help experienced individuals brush up on a few topics, and they can also help novices learn the information from the ground up. Whether you want to start from the first lesson in the chapter or skip around to the few lessons you need to review, the choice is up to you. At the end of the chapter, you should have the skills to:

  • Describe thermochemistry and state functions
  • Identify the First and Second Laws of Thermodynamics
  • Analyze how energy transfers work in chemical and physical processes
  • Check out the implications of Hess's Law on reaction calculations
  • Define Gibbs free energy and spontaneous reactions

Preparing for a major exam is stressful enough, so we want to make your study experience as easy as possible. To do so, all of our lessons, chapter guides, assessment tools, and everything else we offer can be accessed 24/7 online. You don't have to worry about books or extra materials, because we keep everything for you in one, easy-to-navigate location. We even give you a personalized user dashboard to keep you organized.

State Functions in Thermochemistry

1. State Functions in Thermochemistry

This lesson defines state functions and explains why state functions are so useful in thermochemistry and thermodynamics. You'll also see a few examples of common state functions.

First Law of Thermodynamics: Law of Conservation of Energy

2. First Law of Thermodynamics: Law of Conservation of Energy

This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.

Second Law of Thermodynamics: Entropy and Systems

3. 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.

Enthalpy: Energy Transfer in Physical and Chemical Processes

4. Enthalpy: Energy Transfer in Physical and Chemical Processes

This video explores the relationship between chemistry and energy. We learn the general properties of energy and the concepts of temperature and heat. We will learn about energy flow and consider the enthalpy change during chemical reactions.

Using Hess's Law to Calculate the Change in Enthalpy of a Reaction

5. Using Hess's Law to Calculate the Change in Enthalpy of a Reaction

Want to make sure you don't blow yourself up during a chemical reaction? This lesson will help you avoid this by teaching you Hess's Law. This is one way to calculate the heat transferred, or enthalpy change, of a chemical reaction.

Spontaneous Reactions & Gibbs Free Energy

6. Spontaneous Reactions & Gibbs Free Energy

In this lesson, we will learn about spontaneous reactions and how we can use Gibbs free energy to predict them. We will remind ourselves about enthalpy and entropy and discuss the importance of temperature and spontaneity.
