Rates of Reaction Coursework - Hydrogen Peroxide and Catalase My Investigation In this investigation I will be trying to find out if the rate of a reaction changes if the concentration of the substance is altered. This will happen if the Hydrogen peroxide is decompostured. Hydrogen peroxide (H202) is a clear poisonous liquid, which is produced during respiration. If this builds up inside the body it can kill, so an enzyme called CATALASE stops this from happening by breaking down the build up. More about Hydrogen Peroxide will be explained in my knowledge. The decomposition of Hydrogen peroxide looks like this: 2H2 O2 Catalase 2H2O+02 Prediction I think that the higher the concentration of Hydrogen Peroxide, the more bubbles will come out. The purer the Hydrogen Peroxide, the quicker the reaction rate. Because I am going to change the concentration of Hydrogen Peroxide after each experiment, I think that fewer bubbles...
