Decomposition of hydrogen peroxide lab essay
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 . In conclusion it was found that the activation energy of the decomposition of hydrogen peroxide with the help of the catalyst ki is when compared to an actual value there was a percent difference of 43%. In the lab it was shown that the natural decomposition hydrogen peroxide is slower than decomposition taking place with the addition of enzymes if hydrogen peroxide was required to decompose naturally, life could not survive. Measuring the heat of decomposition of hydrogen peroxide project description it is an experiment divided in 2 part 1st week and 2nd week done by 4 students group a (my group) & group b all the details, procedures, data sheets, data calculations, excel data sheet will be attached to the order.
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 however, the decomposition takes place very slowly this is an experiment most students in chemistry lab are familiar .

The decomposition of h2o2 (hydrogen peroxide) into h2o and o2 is a spontaneous reaction that needs an enzyme to speed up the reaction to become efficient the chemical equation is: 2 h2o2 ïƒ 2 h2o + o2. In this lab, we will perform the catalyzed decomposition of hydrogen peroxide under various conditions we will record the trials using a gas pressure sensor in a lab quest and analyze graphs of the data from this analysis, we will determine the rate constant, the activation energy and the rate law . Introduction: in this week’s lab experiment, the rate of decomposition of hydrogen peroxide forming oxygen gas will be observed and studied.
A classic example of this is an enzyme lab many biology students complete the reaction is the decomposition of hydrogen peroxide which is catalyzed by an enzyme called catalase. The decomposition of h 2 o 2 into o 2 and h 2 species can be viewed as the kinetically preferred reaction pathway for dehydrogenation of hydrogen peroxide over sicnts there is also a curvature effect on the dehydrogenation kinetics of hydrogen peroxide, that small diameter sicnts with large curvature would be beneficial for decomposition of h .
