This experiment will investigate the factors that affect the rate of reaction of the enzyme catalyse‚ an enzyme found in food such as potato and liver. Catalyse is used to remove hydrogen peroxide from cells. The enzyme speeds up the rate of decomposition of hydrogen peroxide into water and oxygen. The reaction is: Catalyse is able to speed up the process because the enzyme lowers the activation energy of the reaction. This means that the free energy required for the reaction to take place

Kinetics of the Decomposition of Hydrogen Peroxide Lab Introduction: In this week’s lab experiment‚ the rate of decomposition of hydrogen peroxide forming oxygen gas will be observed and studied. Since the rate of a chemical reaction is dependent on two things; the concentrations of the reactants and the temperature at which the process is performed‚ the rate can be measured at which a reactant disappears or at which a product appears. When measuring the rate‚ the rate law will be applied. The

"To See What Factors Affect The Decomposition Of Hydrogen Peroxide By The Enzyme Catalase Which Is Found In The Liver" Introduction: Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without them the reactions would be so slow that life would grind to a halt. Enzymes work by when a substrate molecule bumps into a molecule of the right enzyme‚ it fits into a depression on the surface of the enzyme molecule. This depression is called the

Chemical Kinetics of Hydrogen Peroxide Decomposition Purpose The purpose of this experiment was to determine the rate equation for the catalyzed decomposition of hydrogen peroxide H2O2. Procedure The procedure for this lab can be found on pages 36 - 40 in “General Chemistry CHE111L Laboratory Manual Spring 2014.” Data Tables Carbon copies of data tables and the graph have been attached to the back of this lab report. Calculations 30 mL of

Investigating Factors that Affect the Rate of Reaction of the Decomposition of Hydrogen Peroxide Emilio Lanza Introduction- In this experiment‚ the rate of reaction‚ calculated in kPa sec-1‚ of the decomposition of hydrogen peroxide will be investigated to see how the change in concentration of hydrogen peroxide and the change in temperature affect the rate of reaction. The data will be collected by measuring the gas pressure. The product of Hydrogen Peroxide is oxygen in a gas state thus

The Enthalpy Change of the Decomposition of Calcium Carbonate _INTRODUCTION_ RESEARCH QUESTION: What is the enthalpy change of the decomposition of calcium carbonate? BACKGROUND: Enthalpy in chemistry can be thought of as the energy contained within the bonds‚ or the internal energy‚ but it is not heat and you can only measure changes in it. When bond bonds break in the reactants energy is given off‚ when bonds form‚ energy is absorbed. If the energy absorbed is less than the energy released

businesspeople need to know how to influence and communicate with members of cultures other than their own (Adler and Grahamd (1989)). Through the analysis of the case study on the joint venture of the France based company Alcatel and the U.S. based company Lucent Technologies‚ issues of cross-cultural management‚ the weakness and strength of an international joint venture‚ including the rights and wrongs of the particular case study will be discussed. As Shenkar (2001)said in an article‚ establishing a measure

Purpose Since there are two possible oxidation numbers for the iron nails‚ by this experiment we will need to determine the actual oxidation number of the iron in this experiment. Hypothesis As said in the introduction there will be two possible decomposition reactions: Fe (Ⅱ) + CuCl2 (aq) → Cu + FeCl2 2Fe (Ш) + 3CuCl2 (aq) → 3Cu + 2FeCl2 We can measure the mass of the two iron nails‚ and the copper after the reaction. Thus‚ we can compare the ratio of the mole and the mass of iron and copper. Procedure

Decomposition of Sodium Chlorate to Create Oxygen Gas Introduction: There are several types of chemical reactions. Those reactions include synthesis‚ decomposition‚ single replacement‚ and double replacement. In this experiment‚ we will be decomposing sodium chlorate to create oxygen gas. In a decomposition reaction‚ a chemical compound is being separated into elements or simpler compounds. AB → A + B is a simple way of expressing what happens in a decomposition reaction‚ AB break down into A
