About This Chapter
Equilibrium in Chemistry Basics - Chapter Summary
To refresh your knowledge of equilibrium in chemistry, simply work through this fun and convenient online study guide chapter. The chapter's bite-sized video lessons show you the differences between equilibrium types, as well as the methods that are used to calculate equilibrium in chemical solutions. By the end of the chapter, you should be equipped to:
- Compare chemical and dynamic equilibrium
- Summarize LeChatelier's principle
- Define the equilibrium constant and the reaction quotient
- Calculate equilibrium using RICE tables
- Define solubility equilibrium and acid-base equilibrium
To help you reinforce your understanding of these basic chemical equilibrium topics, we've included short quizzes throughout the chapter. The Ask the Expert feature allows you to submit any questions you may have about the chapter topics, and the transcripts are available to print out for offline study. Finally, at the end of the chapter, you'll have the opportunity to take a comprehensive exam that goes over essential equilibrium terms, concepts and formulas.
1. 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.
2. 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.
3. 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!
4. Using a RICE Table in Equilibrium Calculations
Learn what the RICE table is and how to fill in the table with the reaction, initial concentration, change in concentration and amount of product and reactants at equilibrium. Learn how to use the RICE table to calculate the concentrations and amounts and the equilibrium constant of equations at equilibrium.
5. 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.
6. Acid-Base Equilibrium: Calculating the Ka or Kb of a Solution
In this lesson, you will review acid and base strength and acid and base dissociation. You will then learn what acid and base dissociation constants (Ka and Kb) are, what they mean, and how to perform calculations involving them.
