Katie Sutton Chemistry Coursework Investigating Rates of Reaction (suspension) Sodium + Hydrochloric Sodium + Sulphur + Water + Sulphur Thiosulphate Acid Chloride Dioxide Na2S2O3 + 2HCl NaCl + SO2 + H2O + S (aq) (aq) (aq) (g) (l) (s) I am going to investigate the effect of temperature on the rate of a chemical reaction, between Sodium Thiosulphate and Hydrochloric Acid. I am going to follow the course of the reaction by drawing a cross on a sheet of paper and placing the beaker containing the reaction over it, I will wait and time with a stop watch until the (sulphur) solid is thick enough to obliterate the cross on the paper in a 'cloudy' liquid. I predict that the reaction time will change when the temperature is altered. I think that the higher the temperature the less time the course of reaction will take. This is because the particles move faster, which causes the likelihood of...
