Prediction I think that the rate of reaction will differ with how strong or weak the reacting particles are. If the reacting particles are of a strong concentration it will have a quick rate of reaction. If the reacting particles are of a weak concentration it will have a slow rate of reaction. This is because for a reaction to occur the reacting particles need to collide, the harder the particles collide, and the more successful the reaction will be. The stronger the solution the more particles that will collide therefore the rate of reaction will be much quicker. High Concentration Low Concentration Planning During the experiment the variables that I will use is the concentration of the reacting particles of sodium thiosulphate and water. Starting with a strong concentration of pure sodium thiosulphate I will gradually dilute it with water. I will keep the volume of the water and sodium thiosulphate the same...
