Chemistry Coursework I am going to investigate the affect on the rate of reaction when I change the concentration of 0.1M sodium thiosulphate solution. The variables that I could change:> The volume of sodium thiosulphate, hydrochloric acid and water.> The temperature of the solution.> The different concentrations of thiosulphate solution/hydrochloric acid.> The use of a catalyst, different catalysts. This would happen because:> If I were to increase the volume of sodium thiosulphate solution and hydrochloric, but not water, then there would be a higher concentration of these two solutions, meaning that the reaction will occur faster. This is because there are more particles of these solutions that will collide with each other and cause a reaction. However, increasing the volume of water and not the other solutions means there will be a lower concentration and the reaction will occur slower.> If I were to increase the temperature of the solution, the reaction would occur...
