Rates of reaction:- sodium thiosulphate + hydrochloric acid

Plan:-

We must produce a piece of coursework investigating the rates of reaction, and the effect that changing one particular variable has on the reaction time. The rate of reaction is the time it takes one or more of the reactants to react or the time it takes to produce a new product from a chemical reaction. To work out the reaction time we use the formula.

1 divided by time taken for reaction

There are five factors which affect the rate of a reaction, according to the collision theory of reacting particles:

1. temperature of solution,

2. concentration of solution,

3. pressure of gases in reaction,

4. surface area of reactants,

5. Catalysts.

For my preliminary experiments I have chosen to investigate the effect temperature and concentration have on a reaction. I have chosen to investigate these reactants because the are the most practical for the lab and equipment that I have available to use also it would take to much time to prepare a solid in powdered and unpowdered form, and
