Decomposition of Hydrogen Peroxide Investigation Hypothesis The inorganic catalysts will aid the breakdown of hydrogen peroxide as they all contain catalase. However, the catalyst with the highest concentration of catalase, liver, will help hydrogen peroxide compose most readily and thus give off the most oxygen. There are four main factors which affect the rate of chemical reactions: * Temperature * Concentration * Surface area * Presence of catalyst. For any reaction to take place, the reactants must come into contact. Anything which increases the chances of this happening will increase the rate of reaction. The reacting particles do not just have to bump into one another, they must collide with sufficient energy, and otherwise they do not react. The minimum amount of energy required is known as the activation energy. The more the particles collide in a given time, the faster the rate of reaction, this is called collision theory. Temperature: The higher the temperature at which the reaction...
