1.1 Review of Thermodynamic Principles

INTRODUCTION

As you can see from the Lesson Schedule, this course is divided into six general topics. We will spend anywhere from one to four weeks on each topic. Each topic is in turn divided into one or more modules. The website has a page corresponding to each module. On the page for each module you will find the following information: 

  1. A list of learning objectives for the module to help guide your studies.
  2. Assigned reading corresponding to the module.
  3. Lecture notes for the module in the form of both Powerpoint and PDF files.
  4. Audio files to accompany the Powerpoint files.
  5. Quizzes relevant to the module.
  6. Threaded discussion relevant to the module.
  7. Problem sets relevant to the module.

LECTURES: You may access all the lecture material via the web page for each module of each lesson. You may use the Powerpoint version or the PDF version of the slides, coupled with the Real Player audio file. You must open these files separately. Also, when using the Powerpoint version of the slides, it is highly recommended that you use Internet Explorer as your browser. Important symbols may not come out correctly in other browsers. I know for sure there are problems viewing the symbols using Netscape. I have not tested FireFox.

QUIZZES: For several modules of each lesson, there are self-test quizzes available on web CT that should help you assess how well you are mastering fundamental concepts, definitions, etc. These quizzes will not form part of your grade. You may take the quizzes as many times as you like. It is recommended that you take the quizzes until you can obtain a perfect score.

HOMEWORK: There will be one homework assignment due for most of the modules. You will download your homework assignment from the web. The due dates will be posted on the schedule page of the website. The solutions to the problem set will be posted on the web immediately after class on the due date. Therefore, NO LATE HOMEWORK ASSIGNMENTS CAN BE ACCEPTED FOR ANY REASON WHATSOEVER. Instructions for submitting homework are given on the Help page of this website, and on the page for each Homework Assignment. ALL HOMEWORK MUST BE RECEIVED BY 4:00 PM PACIFIC TIME ON THE DATE IT IS DUE!!

OVERVIEW

The goal of this lesson is to briefly review some of the important principles of thermodynamics that will be required in the course. These include the concepts of chemical equilibrium, activity and the equilibrium constant.

LEARNING OBJECTIVES

  • Review the concept of chemical equilibrium.
  • Review the use of the Gibbs free energy as a criterion of equilibrium.
  • Define the equilibrium constant and review Le Chatlier's Principle.
  • Review the concept of activity and the activity coefficient.
  • Review the relationship between the Gibbs free energy of reaction and the equilibrium constant.
  • Review the van't Hoff equation for the temperature dependence of the equilibrium constant.

KEY CONCEPTS

  1. The meaning of chemical equilibrium
  2. How chemical activity is related to concentration via the activity coefficient
  3. The definition of the equilibrium constant, and how to formulate and use this constant
  4. How to calculate equilibrium constants at different temperatures using the van’t Hoff equation
