Decomposition of Hydrogen peroxide SCIENTIFIC BACKGROUND INFORMATION I will investigate the factor that affect rate of reaction of the enzyme catalase. Catalase is an enzyme found in living cells i.e. potato and liver. It promotes the conversion of hydrogen peroxide a powerful and potentially harmful oxidising agent to water and molecular oxygen (the enzyme increases the rate of decomposition of hydrogen peroxide into water and oxygen). The reaction is: - 2H O --> 2H O + O Enzymes are biological catalysts that increase the rate of a reaction. The reactant substances upon which an enzyme acts are termed the substrates. The substances produced as a result of the reaction are the products. Enzyme-controlled reactions are mostly reversible and involve the formation of an intermediate enzyme-substrate complex. Activation energy In order to start a reaction, chemical bonds must be broken so that new bonds can be formed. The energy necessary to break these bonds...
