Experiment #17 was discussed at the opening of lecture today. In this experiment you will collect data to determine the rate constant and rate law for a chromium reaction. You will illustrate the principles from Chapter 14 to plot experimental data using Excel. Detailed instructions for this lab can be found on Dr. Zellmer's web-site:
Experiment #17 Lab Instructions
After discussing Lab #17 we continued with reaction mechanisms (Section 14.6). If we are given the rate law and the overall chemical reaction we can propose a reaction mechanisms, which shows the intermediates in a reaction. We can also give the overall reaction and the rate law if we are given all the elementary steps for a reaction mechanism.
On Wednesday I will start class by going over the grades on the first midterm and I will discuss how the grades are assigned, then we will finish up Chapter 14 with transition state theory and catalysis.
