Decomposition of hydrogen peroxide essay - decomposition of hydrogen peroxide aim: my aim in this experiment is to investigate the effect of changing the concentration of the substance (hydrogen peroxide) in an enzyme controlled reaction. As hydrogen peroxide is active and harmful to cells and tissues of organisms, its decomposition therefore needs to be speeded up greatly in order to prevent it from intoxication in the cell we will write a custom essay sample on the effect of catalase concentration on the rate of decomposition of hydrogen peroxide specifically for you.
Catalase is a red, crystalline enzyme that consists of a protein complex with haematin groups and catalyses the decomposition of hydrogen peroxide into water and oxygen: 2h2o2 – 2h2o + o2 hydrogen peroxide is a powerful oxidising substance. Decomposition of hydrogen peroxide in a closed vessel, you will be able to determine the reaction rate as a function of the pressure increase in the vessel that is caused by the production of oxygen gas if you vary the initial molar concentration of the h 2 o 2. The balanced equation of the decomposition reaction of hydrogen peroxide is that 2h2o2 decomposes into the products 2h2o + o2(g) the resulting products are water and oxygen gas.
