Investigating the effects of concentration on rates of reaction Prediction I predict that the higher the concentration, the quicker the rate of reaction. This will happen because in a higher concentration of a solution, there will be many more particles in the higher and collisions will occur more frequently. The more frequent these collisions, the greater the chance they have of reacting. This means the rate of chemical reaction will increase if the concentration of the reactants is increased. Plan I am going to make a solution of sodium thiosulphate and hydrochloric acid and time it to see how long they take to completely react and repeat it for different concentrations. Firstly I will measure out 50ml of Na S O (aq) using a measuring cylinder and then pour it into a conical flask with a piece of card with a visible 'X' on it. Then I will measure 5ml of 2HCL(aq) and then...
