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.

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

kind of role does hydrogen peroxide and a liver have in their chemical reaction? In the experiment‚ we saw they had a reaction‚ but completed further tests to determine whether they changed after the reaction. Hydrogen peroxide is chemically changed into water and the liver is broken down in the reaction. In the experiment‚ a fresh piece of chicken liver was put into a test tube filled with 3% hydrogen peroxide. We knew a reaction was taking place because the hydrogen peroxide started to foam and

because it can cause hazard for the humans and possibly to the environment‚ the hydrogen peroxide is now as an alternative to replace formalin for a common treatment for parasites (Pedersen and Flemming‚ 2010). Graslund et al‚ 1 (2003) showed that the hydrogen peroxide acts as chemical that served several purposes such as to eliminate bacteria‚ parasite and also algae in shrimp farming. However‚ the hydrogen peroxide still can be hazardous for the health of farmers (Boyd‚ 1999) and also affect

An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts‚ which speed up the rate of reaction without being used up during the reaction‚ which take place in living organisms. They do this by

As I am helping her prep for the big day‚ I’m glancing over at the refrigerator. I walk over and notice lots of pictures of her two sons‚ name Chris and Jimmy. The pictures look like it was taken many years ago. One of the pictures had a pyramid behind them‚ looks like they went on vacation like Mexico or Egypt. I also see

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 it is mandatory to use the

without the worry. This applies greatly to the invention of the refrigerator. For decades people have been practicing inconvenient refrigeration techniques to prevent food spoilage but in 1834 Jacob Perkins built the first practical refrigerating machine through the ideas he encountered from other people. He modified the findings of Oliver Evans’s invention‚ the vapor-compression refrigeration and then built his idea of the refrigerator unit. Before Perkins development in 1834‚ ice was the only convenience
