To investigate the amount of oxygen as we vary the rate of reaction. Aim To find the effect of reaction of Catalase in potato with Hydrogen peroxide when changing the temperature. Prediction I think that when the temperature is increased the rate of reaction will increase i.e. more oxygen will be given off. I think that after a certain temperature the reaction will not increase any more and then decrease rapidly because the enzymes will start to be denatured. This will occur at around 40° C and will be entirely denatured at around 50° C. I also believe that up to 40°C if the temperature is increased by 10°C the rate will be doubled. This is what I think my graph will look like: This is because hydrogen peroxide will dissociate itself to form water and oxygen. But this takes a long time so catalase in the potato is used to speed up the...
