About This Chapter
CEOE Physical Science: Equilibrium - Chapter Summary
In an effort to get ready for CEOE Physical Science test questions, explore the equilibrium concepts in this chapter. Learn about the statements made by LeChatelier's principle and discover what a RICE table is and how to illustrate it. Watch the videos and improve your ability to write an equilibrium expression, solve an equilibrium equation or calculate a buffered solution's pH levels. Discover how a titration curve is created and learn to use dissociation constants for acid and base dissociates. Work through this chapter in order to:
- Define chemical equilibrium and acid-base buffers
- Explain LeChatelier's principle
- Distinguish between equilibrium constant and equilibrium quotient
- Perform calculations with a RICE table
- Define and use solubility constant
- Understand the common ion effect and acid-base equilibrium
- Explain titration and titration overview curves
Get in study time at your own pace as you prepare for the CEOE Physical Science examination, which Oklahoma uses as a requirement for certification to teach the subject. Led by instructors and presented online, these lessons are fun and flexible. Study visually by watching the animated lessons on your mobile device or scan the transcripts to determine how much you already know about equilibrium. Pop-up quizzes will test your retention of related concepts.
CEOE Physical Science: Equilibrium Chapter Objectives
Divided into three subareas, the computer-based CEOE Physical Science examination requires a passing score of 240. You'll provide answers to questions on equilibrium, reaction rates, LeChatelier's principle and more during Subtest 3, Structure of Matter and Changes in Matter, which equals 29% of the test score. In less than four hours, you'll be required to complete one constructed-response assignment and 80 selected-response questions that stretch across all three subareas.
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.
7. 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.
8. Acid-Base Buffers: Calculating the pH of a Buffered Solution
Learn what a buffer is, how it works, and why we benefit from having our blood buffered. Learn how to calculate the pH of a buffered solution before an acid or base is added and how the pH changes after an acid or base is added.
9. Titration of a Strong Acid or a Strong Base
Discover what titration is and how to calculate the concentration of an acid or base that has been titrated to equivalence. Learn the meaning of titrant, standard solution and equivalence point. Study titration curves and learn how to determine pH during any point of a titration between a strong acid and strong base.
10. Titration: Overview, Curves & Calculations
Titrations are useful to determine the molarity of a sample or a compound in a sample. We will learn how to perform a titration and how to calculate the molarity of a sample based on the titration.
