Rate of Reaction Aim: The aim is to see how the concentration of sodiumthiosulphate (Na2 S2 03) affects the rate of reaction with hydrochloric acid (hcl) once it is diluted with water. Scientific Background: The reaction taking place in this experiment in a word and chemical equation is: Sodium-ThioSulphate + Hydrochloric Acid ---> Sodium Chloride + Water + Sulphur + Sulphur dioxide Na2 S2 03 + 2HCL ---> 2Na Cl + H20 + S + S02 For a reaction to occur not only must particles collide with one and other but they must have enough energy so that original bonds are broken and new bonds formed. The energy needed to break a mole of bonds is known as bond energy. If the collision has insufficient energy no reaction occurs. The more successful collisions, the faster the reaction. Successful collisions depend on particles moving faster to increase the chance of colliding. Increasing the...
