In this section we will begin to explore the equilibrium constant, K. The value of K has meaning (product- or reactant-favored), and calculating equilibrium concentrations of reactants and products is important. We will also explore the value of Le Chatelier's Principle, a concept we will use throughout all of CH 223 this quarter.

Here's what is happening in week 2 of CH 223:

• Explore the material in Chapter 13. There are several tools to help you learn the material.... they include:
  • Read Chapter 13 in the textbook
  • Watch the Complete Lectures for Chapter Thirteen here: Part I, Part II.
  • Lecture videos for Chapter 13 can be found on YouTube and as a Podcast.
  • Chapter Guide One (online learning materials for Chapter 13) might be helpful
  • "Mini video lectures" can be found in the Screencasts page for CH 223 under Chapter 13.
  • The Concept Guide for Chapter 13 and other Chapter 13 handouts might prove useful.
• Due: Problem Set #1 which covers problems from Chapter 13.
  • Use this link to get the Spring 2025 version of problem set #1.
  • Section 01 and Section H1 will bring the problem set to recitation to be self-corrected.
  • Practice Problem Set #1 might be of help while completing problem set #1; answers are included at the end of the document.
• This Week: Quiz #1
  • Section 01 and Section H1 will take the quiz in class during recitation in AC 2501.
  • Sample Quiz #1 (answers) might be useful to help you prepare and study.
• Due: The Determination of an Equilibrium Constant (in class) Lab and the "Introduce Yourself (in class)" lab are due during recitation
• I also recommend you pick a Class Presentation topic which will help you in your Class Presentation assignment.
  • More information about the Class Presentation can be found here.
  • Use this page to select a topic, then email me which topic you'd like (and include an alternate topic or two, just in case)... I'll get back to you quickly. If you'd like me to pick a topic for you, let me know!
