effect of temperature on catal
Extended Title: "have to draw graphs yourself" To find the rate of reaction of Catalase in potato with Hydrogen peroxide when changing the temperature, i.e. the amount of oxygen produced. 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 beyond a certain temperature the reaction will not increase any more and then decrease rapidly because the enzymes will start to be denatured. The enzymes will start to be denatured 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. Arranius's equation proves this. This is what I think my graph will look like: 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 reaction. The catalase is an enzyme, enzymes are catalysts which control the speeds of chemical reactions in cells, which lower the activation energy needed for particles to react, so that they will react m
