Physical Chemistry
Laidler, Meiser, Sanctuary textbook – Support Portal
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.
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
- Initiation
- Propagation
- Inhibition
- 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.
The usefulness of Enzymes as Biological Catalysts

Fall is creeping into my part of the world; harvest is in full swing and my thoughts are turning now to large dinners with ham, turkey and all the fixings. Of course, one of the things I am most thankful for after such a meal is catalysts.
The term catalyst is commonly used as an expression to identify a person or moment that started an event. In my world, it is a substance that helps speeds things up without being used up. Continue reading
Enzyme Catalysis in Chemical Transformations
Screengrab of animation of Acid-Base catalysis from the Physical Chemistry book
Enzymes are the catalysts of biological systems. They are remarkable molecular designs that determine the pattern of chemical transformations.
The most striking characteristics of enzymes are their catalytic power and specificity. By using the full gamut of intermolecular forces, enzymes bring substrates together in an optimum orientation. Continue reading
Chemical Reactions; What? How much? How fast?

When dealing with chemical reactants, three important questions are usually asked.
(1) What product(s) can be made,
(2) How much can be made and
(3) How fast can it be made. Continue reading
Kinetic law says ‘last will be first’

Reactions are usually complex events. Bonds are broken, formed, stretched and atoms driven by enthalpy and entropy in their marvelous path. From reactants to products, and vice versa.
Even when a system reaches equilibrium, it is very unusual for compounds to rest peacefully; instead, they will start going back and forth in perpetual motion. 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.
