Rates of Reaction Aim: I am trying to find out the rates of reaction and how concentration effects the rates of reaction. Surface area: If the surface area is increased there is more chances of collision. Concentration: The more the particles, the more they will collide. Temperature: The higher the temperature the more they will collide and vibrate. Catalyst: The more the catalyst the faster the reaction. Apparatus: Measuring cylinders, Distilled water, Sodium thicsulphate solution, Hydrochloric acid, Boiling tubes, Labels, Conical flask, Stopwatch, Goggles. Prediction: I predict that the lower the concentration the more time it will take to react. Sodium Thicsulphate Solution Distilled Water Concentration Dm3 (moles) 50 0 0.1 40 10 0.08 30 20 0.06 20 30 0.04 10 40 0.02 Method: The table above shows how you make up the concentration. 1. Mix sodium thicsulphate solution with distilled water as the table shows. 2. We measure using measuring cylinders. 500cm3 sodium thicsulphate and 5cm3 of distilled water need to be measured. 3. When it's done use 5cm3...
