Chemistry Coursework The effect of temperature on the rate of reaction Prediction I predict that as the temperature of the reactions increase, the time taken for a reaction to take place will decrease. The more heat in the flame, the more energy. This energy is transferred to the solution; the particles will therefore have more energy. Under high temperatures the particles move faster, vibrate quicker and more violently - the higher the temperature, the faster the particles move. Therefore, with the particles moving around quickly there is a higher chance that they will collide, the more successful collisions the quicker a reaction. The higher the temperature, the quicker the reaction will be. Apparatus Bunsen burner Tripod Gauze Sodium thiosulphate Hydrochloric acid Beaker Stopwatch Scrap paper Pen Method A cross is marked on the piece of paper and a beaker containing 15cm² of sodium thiosulphate solution is put on the cross. The cross should be visible through the solution. 5cm³ of Hydrochloric acid...
