    I've just finished Yr 12 and started Yr 13 Chem. What I am told is that we are doing a practical on measuring the rate of reaction by an initial rate method.

    - decide on which method + reaction to study
    - study how to analyse their data in order to determine the rate of reaction

    When I went to Chemguide, it said there are 2 approaches to this experiment:

    - Investigate what happens to the initial rate of the reaction as you change concentrations
    - follow a particular reaction all the way through

    Then I referred to the Chem handbook and found the 2 experiments

    Pg 97 and 101 - http://filestore.aqa.org.uk/resource...-7405-PHBK.PDF

    At the moment, I have decided to write up this experiment as follows:

    - Introduction
    - Hypothesis
    - Apparatus
    - Risk assessment
    - Method
    - Results
    - Conclusion
    - Evaluation


    1) Do you need like a background/theory to the experiment or not?

    2) My teacher said I need to justify the reason why I chose to use approach 1 or approach 2 in the intro e.g in terms of how easy it is to carry it out, safety etc.
    Any other points I could possibly use?

    Okay im doing a level chem paper 3 tomorrow. You jus need to know what to do and why for the practicals. Mate i dont even know them im gonna try learn them today, but make sure the rest of your chem is up to par cause paper 3 = anythinggggggggg. and 30 marks of multiple choice so basically if you get past the written questions without any troubles, which there arent much of cause of the 30 marks in MC then you should be good. Just get the mc q right too. It might help to get everything right tbh
