... RATE OF REACTION BETWEEN SODIUM THIOSULPHATE AND HYDROCHLORIC ACID Aim: To investigate the rate of reaction between a fixed amount of sodium Thiosulphate and different concentrations of hydrochloric acid. Theory: The factors affecting the rate of reaction are - * Surface area of the reactants * Concentration of the reactants * Temperature at which the reaction occurs * Light * Use of catalyst The definition of collision theory as stated in www.wikipedia.org 'the collision theory assumes that for a reaction to occur the reactant particles must collide, but only a certain fraction of the total collisions, which are called effective collisions, cause the transformation of reactant molecules into products. This is due to the fact that only a fraction of the molecules have sufficient energy and the right orientation at the moment of impact to break the existing bonds and form new bonds. The minimal amount of energy needed so that the molecule is transformed
