Effect of Temperature on Reaction Time We are investigating the reaction rate between sodium thiosulphate and hydrochloric acid with varying temperatures. When these two compounds are reacted they create sodium chloride, water, sulphur dioxide and sulphur. Prediction I predict that the higher the temperature the faster the reaction rate. This is because the particles have more energy to move around and can collide more frequently. We need collisions between particles for reactions to take place. Particles have less energy Particles have more energy Fewer collisions More collisions Slower reaction Faster reaction Apparatus List 1x Heating Apparatus 1x Conical Flask 1x Safety Goggles 1x 10ml Measuring Cylinder 1x 50ml Measuring Cylinder 1x Thermometer 1x Tongs 1x Stopwatch 1x Paper with X marked on Sodium Thiosulphate (0.1M/50cm³ x 15) Hydrochloric Acid (1.0M/5cm³ x 15) Method We will obtain a conical flask and rest it on the paper with the cross on. We then shall put 50cm³ of sodium thiosulphate into the flask and heat it to the desired...
