Factors that affect the rate at which Sodium Thiosulfate (Na2S2O3) reac

I am to investigate the factors that affect the rate at which SodiumThiosulfate (Na2S2O3) reacts with Hydrochloric Acid (HCl).When sodium thiosulfate is mixed with hydrochloric acid, a answertakes place, principal to a precipitate of sulphur be formed. Thisturns the solution cloudy. I shall call this clouding to investigate afactor that affects the rate of reaction, the factor beingtemperature.To do this, I shall react Sodium Thiosulfate with Hydrochloric Acid ata range of temperatures, between 20C and 40C, at 5C intervals,leading to 5 results. The experiment shall be carried out twice, to pop off accuracy, and allowing me to check for agreement between results.I predict that as the temperature that the reaction takes place atincreases, the less time it will take for the reaction to take placeand for the solution to cloud. My prediction is based on the contacttheory, which says that Reacting species must hit together Species must hit together with to a greater extent than the a ctivation energy neededIncreasing the temperature of the atoms taking part makes them operatemore and faster, enabling more collisions to take place, hasten upthe reaction. The added rage energy also allows more collisions tohave the required activation energy, again, speeding up the reaction.In order to make this experiment a bonny test, I changed only one inputvariable, the temperature. I kept the count and concentration of theliquids the same (20m...
