Coursework Assessed Practical An Experiment to investigate the rate of reaction Name: Ruth Fitzpatrick Aim: To investigate a factor that affects the rate of reaction and why? Introduction: I am going to investigate what factors affect the rate of reaction. In particular I will look at how the concentration of the reactants affects the speed of the reaction. To do this I am going to add sodium thiosulphate to different molarities of hydrochloric acid and time how long it takes for the reaction to take place. The equation is as follows: Sodium Thiosulphate + Hydrochloric Acid › Sodium Chloride+ Sulphur Dioxide+ Sulphur + Water (Yellow insoluble solid - precipitate) Na2 S2 O3 + 2H+ CL- › 2Na+CL- + SO2 + S + H2O The chemists who work in industry have to try and produce materials as cheaply as possible. Efficiency is important, and to create an efficient reaction in industry, it should be quick. In order to do this...
