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 reactiontakes place, ahead(p) to a precipitate of sulphur being formed. Thisturns the solution cloudy. I shall use 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, ahead(p) to 5 results. The experiment shall be carried out twice, togive accuracy, and allowing me to check for agreement between results.I predict that as the temperature that the reaction takes place atincreases, the slight time it will take for the reaction to take placeand for the solution to cloud. My prediction is based on the collisiontheory, which says that Reacting species moldiness hit together Species must hit together with more than the activation energy neededIncreasing the temperature of the atoms taking part makes them movemore and faster, enabling more collisions to take place, hie upthe reaction. The added heat energy also allows more collisions tohave the required activation energy, again, speeding up the reaction.In order to make this experiment a fair test, I changed only one inputvariable, the temperature. I kept the amount and concentration of theliquids the same (20m...
