MEGA Chemistry: Chemical Equilibrium - Chapter Summary
The subject matter experts in this chapter present quality lessons designed to help you competently answer questions related to chemical equilibrium on the MEGA Chemistry assessment. The lessons are fun, engaging and comprehensive, making sure you're prepared for the following on exam day:
- Providing the meaning of chemical equilibrium and explaining how it is dynamic
- Explaining how Le Chatelier's principle describes the disruption and re-establishment of equilibrium
- Defining equilibrium constant and reaction quotient
- Describing how to use a RICE table in equilibrium calculations
- Sharing details about solubility equilibrium and how to use a solubility constant in calculations
- Discussing the common ion effect and selective precipitation
You can review the lessons in their video or transcript formats, and access helpful vocabulary words to deepen your understanding of chemical equilibrium. If you choose to review the videos, you can also access timelines that allow you to skip to key topics without watching them in full. Self-assessment quizzes and a chapter exam are available to test your understanding of the lessons.
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. The Common Ion Effect and Selective Precipitation
Learn what the common ion effect is, how to make equilibrium calculations involving it, and how to find the concentrations of ions when adding reactions in equilibrium to solutions that already contain ions.
