Science Coursework- Rates of Reaction

Aim: My aim of my coursework is to investigate factors that affect the rate of reaction. Before I chose what I am going to investigate I first brainstormed some ideas about what affect the rates of reaction/ speeding up reactions. Here are the ideas I came up with:

* Temperature

* Concentration

* Surface area

* Volume of reactants

* Mass of reactants

* Add a catalyst

After looking at these things that would increase a reaction I decided that would investigate concentration. I made this decision because it was an investigation that I would be able carry out in the period of time I was allowed and I had the equipment and solutions available to me, to carry out the investigation. The only other one I could have possibly investigated would have been an Increase in temperature however I decided not to investigate this any further. I did not use either gas or a catalyst, as they would be un-performable investigation to make within a school laboratory. That is why I decided on the variable I did.

Hypothesis: I predict that as I
