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.  I will provide links and videos to assist you with learning the material.

I will combine chapter 6 with chapter 7, Equilibrium, as they are both very short chapters.

Content Review
Textbook: Chapter 6
Mad!Science! Links:  Kinetics

Agenda:
Complete the tasks found here.  You will need to reference this page.
​
Mission 1: Reaction Mechanisms.
Mission Objectives.  You should be able to...  
1.  Explain the factors that affect rates of reaction.
2. Investigate rates of reaction experimentally and evaluate the results.


​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.   
Mission 2: Dem Graphs Again!!! 
Mission Objective.  You should be able to...
1.  Sketch and explain energy profiles with and without catalysts.


​Here is a simple graph from the BBC Bitesize website. 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)...​
Mission Objectives.  You should be able to...
1. 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.


​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.  Copy and paste this link to listen and/or read:  http://study.com/academy/lesson/the-boltzmann-distribution-temperature-and-kinetic-energy-of-gases.html
