As the concentration of the Sodium Thiosulphate increases, so does the number of particles in the solution with the kinetic energy to react. This then gives a higher probability of two molecules colliding and having the energy to react and form the products, one of which is the sulphur precipitate which we are essentially measuring the rate of production in the reaction. This increased rate of reaction would then cause the time taken for the cross to disappear to decrease. From my results and my analysis above you can see clearly that as concentration increases so does the rate and the recorded time of the reaction falls. I feel that my analysis of the results and the trend shown by the graph clearly shows that in my investigation the predictions that rate increases with concentration and rate doubles upon concentration doubling are fully supported.
