Aim. Sodium thiosulphate solution of concentration 40g/litre is poured into a conical flask. When a small volume of dilute hydrochloric acid is produced the mixture goes cloudy. I wish to find out what alters the rates of reactions in this solution. I am going to find out the reaction rate using temperature. Prediction. If the temperature in the solution is high then the molecules which are in the solution gain energy and move at high speed, therefore the chance of the particles colliding is increased which will make the reaction take place a lot quicker. If the temperature is low the particles have less energy and are less likely to collide. Reasons & Explanations. Chemical reactions take place when the particles of the reactant collide. They first have an activation energy which is very low. I have studied that if the temperature in a reactant is high then the particles will collide more often due...
