College Science Bundle: The three college level courses - General Chemistry, General Physics (calculus) and Organic chemistry, bundled together in one package.
High School Science Bundle: The two high school level courses- Introductory Chemistry and General Physics (non- calculus), bundled together into one package. This bundle is very popular with High School and Home School students.
With the holiday season coming up I thought discussing the half-life of beer could be helpful to some
Earlier I had written more about the Chemical Kinetics of getting Sober, but in this clip I’m teaching zeroth order chemical kinetics and the concept of half life. The multimedia is is taken from Chapter 9, section 9.4 of the Physical Chemistry textbook by Lailder, Meiser and Sanctuary.
In this clip I am showing chain reactions, in a class demo, using multimedia from the latest edition of the Physical Chemistry texbook by Laidler, Meiser and Sanctuary. The steps discussed in this clip are
Chemical Kinetics from chapters 9 and 10 contain this multimedia clip that I use in class to show the steps of the chain reaction. This is found on page 10-9 of the text and is also found in the Multimedia table of contents on the side bar.
This clip from the Physical Chemistry book explains how concentration changes with pressure. Changing the pressure on a gas can change the number of moles.
This leads us to the concept of the chemical potential: each compound has a potential to react and has its own molar Gibbs free energy. The greater the chemical potential is negative (at constant T and P) the greater the potential to react and minimize the Gibbs energy for the whole reaction.
In class, I used the animation in chapter 4- Approach equilibrium (page 4.28 of my Physical Chemistry book), to show that the ratio of the forward and reverse rate constants is equal to the equilibrium constant. Continue reading
Here are a couple of clips where I use multimedia from the physical chemistry book, in the classroom, to explain concepts Continue reading
Thermodynamics module
Chapters 1 to 6 of Physical Chemistry - Laidler, Meiser, Sanctuary
Includes multimedia that opens on relevant pages and allows the student to visualize many of the concepts by varying parameters and plotting different graphs. Things students often have difficulty with, such as isothermal, isobaric, isochoric and adiabatic process, are clearly visualized.

Physical Chemistry textbook
by Laidler, Meiser, Sanctuary
This popular Physical Chemistry text book is now available in electronic format. We have preserved much of the material of the former hard copy editions, making changes to improve understanding of the concepts in addition to including some of the recent discoveries in physical chemistry. Many chapters have new sections and the coverage of several chapters has been greatly expanded.
