Housekeeping: Chapter 6 covers kinetics, which means "movement." In the context of chemistry, it refers to the movement of particles. We have covered the meat of kinetics, but now it is time for you to go back and study the bread. I have given you a set of three tasks that you must complete within the next three class periods. I will provide links and videos to assist you with learning the material.
I am going to combine the Chapter 5 exam with Chapter 6, so you will take just one test. It is easier that way and since your exam is scheduled for May 10, you have plenty of time to master the content in Chapter 6.
Content Review
Textbook: Chapter 6
Mad!Science! Links: Kinetics
Agenda:
Complete the tasks found here and in hard copy.
Lesson Objectives: You should be able to:
1. Explain the factors that affect rates of reaction.
2. Construct a Maxwell-Boltzmann energy distribution curve to account for the probability of successful collisions and factors that affect them, including the effect of a catalyst.
3. Investigate rates of reaction experimentally and evaluate the results.
4. Sketch and explain energy profiles with and without catalysts.
Mission 1: Reaction Mechanisms. The mechanism of a chemical reaction is the series of events that takes place as reactants are converted into products. You can read more about it on ChemWiki. The first video, from Brightstorm, introduces the concept of reaction mechanisms. The second video, which is IB, goes into detail about determining rate laws, which we will deal with soon enough.

Mission 2: Dem Graphs Again!!! Here is a simple graph from the BBC Bitesize website. What do you see?
Here's another. What do you see?
The point of Mission 2 is for you to be able to read and interpret different rate graphs and provide a reasonable explanation as to what is going on, so make sure you pay close attention to the graphs in your text.
Mission 3: Dudes Named Max and Bolt (sort of)...The Maxwell-Boltzmann graph is a distribution curve that shows the distribution of particles in a reaction. Below is a picture from chemguide.edu and a quick YouTube video summary. Study.com has a nice, extensive explanation that will help you answer the questions on the sheet.

Homework: It is expected for you to complete the tasks in class and for homework. I have given you three periods, so you have the entire weekend plus Sunday to complete the assignment. So by the end of the period on Sunday, both of you should be handing in separate work. If you hand in one complete set of answers, I will split the grade down the middle.
