By Danielle Choyen 11 Miranda Investigating how changing the temperature affects the rate of reaction. Aim: My aim is to investigate how the temperature of sodium thiosulphate and hydrochloric acid changes the behaviour of the solution. Hypothesis: I predict that if the temperature is heated, the reaction will take place in a faster period of time. This is because in the dilute hydrochloric acid, there aren't many particles, however, when it is heated, the particles vibrate and move around more - in other words, the particles are gaining energy. The Effect of Temperature: When particles are heated up, they have more energy meaning they move around quickly. As they travel faster, there are more collisions in the time. Therefore as we raise the temperature, reactions get faster, whereas if we lower the temperature, the reactions take place slower. This is shown in the diagram below: This diagram shows the reactions the particles undertake as the temperature rises. The...
