Ch 11: ORELA Chemistry: Equilibrium

About This Chapter

The ORELA Chemistry examination for teacher certification includes questions about equilibrium. In order to prepare, you may need to review the subject. Try watching this chapter's online video lessons and taking its quizzes before the examination.

ORELA Chemistry - Equilibrium - Chapter Summary

The online tutorial videos in this chapter will enhance your knowledge of LeChatelier's Principle, solubility constant, the RICE table and other topics. For instance, you'll recall how to make equilibrium concentrations and determine ksp values as you prepare to perform similar operations on the ORELA Chemistry examination. Look to this chapter for assistance with:

  • Comparing chemical and dynamic equilibrium
  • Explaining LeChatelier's Principle
  • Defining equilibrium constant and reaction quotient
  • Filling in a RICE table
  • Discussing solubility equilibrium
  • Describing the common ion effect

Comprised of short video lessons, this chapter will allow you to review what you already know about equilibrium and to possibly discover additional information. Along with written transcripts, the chapter includes pop-up quizzes, navigational video tags and printable worksheets. Experienced instructors provide the narration, and they answer your interactively submitted questions.

ORELA Chemistry - Equilibrium Objectives

Demonstrate what you learned about equilibrium previously and what you reviewed in this chapter when you get to the ORELA Chemistry examination's Chemical Reactions content domain. This content domain accounts for about 23% of the exam's total score. It will test your knowledge of equilibrium principles and ensure your in-depth knowledge of chemical equilibrium and its influence. Display this understanding while answering the 150 multiple-choice questions on the computer-based assessment. As a candidate for a chemistry teaching endorsement, you must observe a three-hour-and-45 minute time limit when testing.

Equilibrium: Chemical and Dynamic

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.

LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

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.

Equilibrium Constant (K) and Reaction Quotient (Q)

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!

Using a RICE Table in Equilibrium Calculations

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.

Solubility Equilibrium: Using a Solubility Constant (Ksp) in Calculations

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.

The Common Ion Effect and Selective Precipitation

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.
