How changing the concentration will change the rate of reaction Aim To find out how changing the concentration of the sodium thiosulphate will change the reaction time. I am going to measure the rate of reaction of sodium thiosulphate and hydrochloric acid. I could use different variables to change the reaction time, these are temperature, concentration and a catalyst. I am going to do one experiment which is changing the concentration. Prediction I predict that the reaction will go faster when the concentration of the reactant is increased, when the experiment is done at room temperature. The higher the concentration of the solution the more particles it will have. The higher the concentration of sodium the faster the reaction. The reaction can only occur when reacting particles collide with each other with enough energy to react. In a high concentration the particles are crowded together because there are more particles, which means they will...
