The half-life of beer calculated with chemical kinetics

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.

Steps in chemical reaction in chemical kinetics

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

  1. Initiation
  2. Propagation
  3. Inhibition
  4. Termination

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.

Chemical Kinetics Part III: Dragons, Caves & Catalysts

A gnome on a gold dragon?

In 1974, Gary Gygax revolutionized the world of fantasy games by publishing the first edition of a game: it was called “Dungeons & Dragons”, and it soon became clear that the potential was so big that other game designers tried to jump into the cart producing similar games (now collectively known as “role-playing games”), even clones or with similar names (“Tunnel & Trolls”, etc).

Chemists and Parents compared, Kinetically speaking

Are we there yet?

Are we there yet? Are we there yet? Are we there yet? Are we there yet?...

Have you ever uttered or heard the phrase: Are we there yet? or How much longer?  Does this prompt flashbacks of your last family vacation!?  We are constantly interested in time, and how fast things happen. Chemists are no different, we merely change the phrasing to: Is it done yet, and how much longer? Continue reading

Kinetics basics in discussing a single reaction

Rate of reactions

When dealing with kinetics, the mechanism or actual pathway followed is required for all chemical equations. If the reaction proceeds exactly as written, it is called elementary.

Usually reactions must be viewed as a series of steps that ultimately combine into the final product. Each of these steps provide insight into the factors that determine the overall speed of the reaction, including the formation of intermediates, species found inside the reaction but do not appear in the final products.

Thermodynamics Module - Physical Chemistry
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 - Laidler, Meiser, Sanctuary
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.
