Aim: In this investigation we are trying to find out how the temperature affects the rate of reaction. Hypothesis: I believe that the higher the temperature, the faster the reaction the reaction between the sodium thiosulphate and hydrochloric acid. This will happen because kinetic energy and the heat energy makes the particles move faster, collide faster and react faster; therefore they can break bonds easier. Scientific Knowledge: Firstly, I will explain the equation needed to follow out the experiment: Na2S2O3 (aq) + 2HCL (aq) 2NaCl (aq) + SO2 (g) + H2O (l) + S (s) This is the experiment that will carried out, I will now put this equation into word format: Sodium Hydrochloric Sodium Sulphur Thiosulphate + Acid Chloride + Dioxide + Water + Sulphur The sodium thiosulphate consists of: two atoms of sodium, two atoms of sulphur and two atoms of oxygen. This combined with the hydrochloric acid creates a chemical reaction and the products...
