1.8 Chemical Reaction Rates
|
This achievement standard involves carrying out a procedure to collect and process primary data and interpret the results, with direction.

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
Below are the two sheets I handed out in class. The template for writing our exam reports and a general guide for scientific writing.
