We shall explore the concept of entropy and how it affects all of science and life as we know it in considerable detail. We shall also discus thermodynamics by exploring Gibbs Free Energy and its relation to enthalpy and entropy. Let me know if you have any questions!

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

• Explore the material in Chapter 12. There are several tools to help you learn the material.... they include:
  • Read Chapter 12 in the textbook
  • Watch the Complete Lectures for Chapter Twelve here: Part I, Part II.
  • Lecture videos for Chapter 12 can be found on YouTube and as a Podcast.
  • Chapter Guide One (online learning materials for Chapter 12) might be helpful
  • "Mini video lectures" can be found in the Screencasts page for CH 223 under Chapter 12.
  • The Concept Guide for Chapter 12 and other Chapter 12 handouts might prove useful.
• Due: Problem Set #1 which covers problems from Chapter 12.
  • Use this link to get the Spring 2026 version of problem set #1, and use this link to find the recitation video which you can use to self correct your work before turning in to the instructor.
  • Practice Problem Set #1 might be of help while completing problem set #1; answers are included at the end of the document.
• This Week: Seminar Quiz #1 and the (actual) Quiz #1
  • All quizzes (Seminar Self Quizzes and actual Quizzes, as well as midterm exams and finals) are closed book / no notes allowed. You cannot use a cell phone or computer; you can have a dedicated calculator and a periodic table (which I will provide) only.
  • First, take Seminar Quiz #1. You will have 20-30 minutes to complete the quiz, and afterwards we will self correct the Quiz as a class before turning it in. If you are late, or do not attend recitation for any reason, your score will be a zero on the Seminar Quiz.
  • After taking the Seminar Quiz, you will take the actual Quiz #1. Quiz #1 will take about 30 minutes and consist of several 'show your work' questions. Turn in the quiz when done (I will pass back any corrected work I have for you at this time.)
  • Sample Quiz #1 (answers at the end) might be useful to help you prepare and study.
• Due: The ""Unknown Chloride" lab
  • Bring the completed lab with you to recitation.
• Due: The Introduce Yourself Assignment
  • Bring the completed assignment with you to recitation.
• Start: The Determination of an Equilibrium Constant Lab
  • Bring a printed copy of the lab with you to recitation.
  • The Lab Introduction Video to this lab might be helpful.
• 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!
  • The deadline for requesting a class presentation topic is Friday, April 17 by 9 AM.
