Chemistry Investigation catalysts Aim Prediction I predict the higher the amount of catalyst used the higher the rate of reaction (ROR). This is because a catalyst speeds up a reaction; so the higher the amount of catalyst used the higher the ROR. The ROR can be measured by the amount of oxygen given off by the reaction. My preliminary work also points out that the higher the amount of catalyst used the more vigorous the reaction, I think this is because. The hydrogen peroxide is slowly breaking down, the catalyst works like an enzyme, it speeds a reaction up without taking part in it. I predict that this reaction will be sped up by the catalyst: 2H202 --> 2H2O+O2 The reaction I predict will take place: 2H202 --> 2H2O+O2 MaO2 A Catalyst is a substance that alters the rate of a chemical reaction without itself undergoing any chemical change. If a reaction has more catalyst present, the catalyst...
