This reaction involves the breakdown of hydrogen peroxide (a poison) by an enzyme (catalase) into non-poisonous water and oxygen. The reaction HYDROGEN PEROXIDE WATER+ OXYGEN Catalase 2H2O2 2H2O + O2 To show this reaction we are going to add a piece of potato into some hydrogen peroxide. We are then going to look at the rate of reaction between the two by changing the temperature or the concentration of hydrogen peroxide...
