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

"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

Changes‚ Changes‚ and More Changes Hudson County Community College isn’t a perfect school‚ but there are a lot of things that they have room to improve on. I honestly don’t have many complaints about this school‚ I feel alright about it‚ I am not impressed but I am also not outraged by anything. Even though I don’t have many complaints about this school it doesn’t mean that I don’t feel that they have things that they should improve on. The biggest problem I have with this school is the service

"There is nothing permanent in life except change‚" said philosopher Heraclitus. Others have called change or variety as ’the spice of life’. So‚ changes (shuffle or reshuffle) in the government from time to time should come as no surprise to anyone‚ though changes in the political arena are often viewed with suspicion. Change is in the very nature of being. Every new day is different from the previous day. Body metabolism is one such process as also growth of trees and revolving of planets. Tides

Change can be both negative and positive‚ bringing about unexpected consequences. In both of the texts‚ the personas are widowers‚ struggling to handle their changed situation created by the death of their loved one. We can see the unexpected consequence of the loneliness they experience and the hope that they have in the midst of despair. The first text ‘Widower in the country’ by Less Murray uses a slow and reflective that emphasises the personas isolation and grief and to explore his reflections

Change is the alteration of a physical‚ spiritual or emotional state over a period of time. These changes are evident in the three texts studied and will be discussed during this essay. Ad-VERSE-ity - a verse novella - was the first core text studied composed by students from Collingwood Alternative School in collaboration with published poet Amelia Walker. The second text studied was a reflective short story written by Hannah Roberts‚ which deals with the narrator remembering her childhood experiences
