1.8.1 Collision Theory

Molecules must collide with enough energy AND in the correct orientation in order for a reaction to take place.  

1.8.2 Factors affecting the Rates of Chemical Reactions

Factors affecting rates of reaction:
     Concentration
     Surface area
     Temperature
     Catalyst
Use Collision Theory to explain factors (includes activation energy)





Homework
: In your own words, describe the two main factors in collision theory.  Then use collision theory to describe how each factor (above) effects the rate of a chemical reaction.

1.8.3 Making solutions with variable concentrations

We will modify the experiment below and make several concentrations of HCl.

1.8.5 Developing an Investigation Method 

We will be investigating the use of catalysts and the rate of a reaction.  We will be looking at the decomposition of Hydrogen Peroxide (H2O2) to Water (H2O) and Oxygen gas (O2) with the aid of a catalyst.
After we investigate various methods of collecting and measuring gas production, you will develop a method to test the rate of a reaction while changing either:
The catalyst used, or
The concentration of a single catalyst
You will first write up your method, then carry out your tests, analyze your data, interpret and discuss your results, and write a conclusion.

1.8.6 Plan and carry out an investigation on the effect of either temperature or concentration on the rate of reaction

1.8.7 How to write a Scientific Report

Here are two links to websites explaining how to write a scientific report
The Structure of Scientific Reports
Guide: Writing the Scientific Paper
Below are the two sheets I handed out in class.  The template for writing our exam reports and a general guide for scientific writing.
