Introduction Aim: - To find out what factors affect the decomposition of Hydrogen Peroxide. The substances that I am going to use in this investigation are Manganese Dioxide and Hydrogen Peroxide. The Manganese Dioxide is a chemical catalyst and will be used to speed up the breaking down of Hydrogen Peroxide. I am using a chemical catalyst because it would give a more accurate result compared to organic or biological catalysts. This because organic and biological catalysts are enzymes, which require a certain temperature and will need to be kept constant as they work best between that temperatures. For example, 37 degrees centigrade to 40 degrees centigrade are temperatures when enzymes work best. This is because enzymes are found in the human body and are used for digestion. Also the human body has a body temperature of 37 degrees centigrade, which is why the enzymes work best at that temperature. ...
