We took a look at additional approximation methods to handle more complex mechanisms. The application to some organic systems was also discussed.
A new homework (Homework #9) was distributed and is due next Monday (11/23).
The third exam (take-home) will be distributed on Monday, 11/23 and will be due Monday 11/30.

We looked at some examples of “simple” mechanisms. We explored the analytical solutions to the care of parallel reactions and began to discuss consecutive reactions. Exam 2 was returned and the solutions are posted on the course website.

We reviewed the use of integrated rate laws in determining rate expressions. We then turned our attention to mechanisms and elementary reactions.

After a summary of some overarching thermodynamics concepts, we began to discus chemical kinetics. We looked at several ways to write the rate of a chemical reaction and the associated rate law.

We explored a more complex binary system where the liquid is nearly ideal and there is limited solid solubility.
Exam 2 was also distributed. It is due in-class on Monday and must be returned in person.

We talked a bit more about ideal binary phase diagrams and the associated cooling curves. We then discussed the case of chemical interactions through the use of activity and the activity coefficient. Finally we started a discussion of a model on non-ideality, the regular solution model.

We saw how we can construct an ideal binary phase diagram (lens diagram) from our expression for the free energy of mixing of two ideal components. Our next step is to see what information this type of diagram gives us.
Solutions to Homework #7 have been posted, as well as last year’s Exam 2.

We developed the beginnings of an ideal binary phase diagram for a two component system that can exist in the solid and liquid phase.
