Experiment to find the relationship between the concentration of Sodium Thiosulphate and the rate which it reacts with Hydrochloric acid. Introduction The rate of reaction is measured by finding the quantity of product made in a certain time. The rate of reaction can be made faster by an increase of temperature, adding a catalyst, increasing concentration or pressure or making the reactants surface area larger. An increase in temperature causes the particles of the reactants to gain more energy and move faster. Collision theory states that this results in more collisions and more of these collisions will have enough energy to cause a reaction. By adding a catalyst the particles will stick to the sides of the catalyst and this increases the rate of reaction. By increasing the surface area there is more surface for the particles to collide with thus causing more collisions and increasing the rate of reaction. Finally...
