HCL and sodium thiosulphate In my investigation I am going to investigate which factors affect the rate of reaction. The rate of reaction depends on four factors and these are the possible factors which I could investigate. § Temperature § Concentration § Catalyst § Size of particles (surface area) I have chosen to investigate the concentration of hydrochloric acid and how it affects the rate of reaction of Sodium Thiosulphate. To make my experiment a fair test I am going to use the same solutions. I will repeat the experiment again so that I will have two pairs of results and then get an average set of results. This will allow me to have a set of accurate results. Analysis: As I mentioned before, the rates of reaction depends on four things. All four methods of increasing the rate of reaction can be explained in terms of increasing the number of collisions. Temperature increases the number of collisions. When the...
