This investigation is geared towards observing the enzyme reaction times in Solanum tuberosum, also known as the common potato, depending on the temperature of the catalase. During the lab, students tested the reaction times of the catalase when placed in hydrogen peroxide when the…
Most corrosion is an electrochemical reaction. Anything that affects the speed of the chemical reaction will in turn affect the amount of current flow, which will affect the rate of corrosion. The rate of corrosion is directly proportional to the amount of current in the electrochemical corrosion cell. If the current can be measured accurately, then an exact calculation of the metal loss can be made.

Concentration on Catalase Reactions
Biol 101 Lab
February 10, 2016
The human body contains thousands of tiny structures called enzymes that perform specific functions. One enzyme called “Catalase” is often used to regulate the amount of a toxic compound, hydrogen peroxide, in the body. The purpose of this experiment was find the different factors that can affect Catalase-Peroxide reactions. The first part of this experiment demonstrated that catalase reactions with…
The role of enzymes play a large role in the survival of organisms through catalysis of reactions that keep them alive and functioning. The purpose of this experiment was to measure reaction activity over time and how substrate concentration affects their activity level. A supernatant was made through the dilution of blended potato extract. Then the supernatant was mixed with catechol and the reaction rate was measured in units of absorbance through a spectrophotometer every 30 seconds for ten…
The results of the lab show the decomposition rate of H2O2 at various amounts of KI, H2O, and H2O2. In addition, the effect of temperature on the rate of the reaction can also be seen in the results.
Figure 1 Figure 2
Figures 1,2 and 3 represent the results obtained from the keeping the amount of KI constant and varying the amount of H2O2 and water. It can be seen that when H2O2 is doubled (Figure 1 to Figure 2) the rate is also doubled from 0.0368 mL/s to 0.0723 mL/s. When the…
volume of gas indicates a constant enzyme reaction rate. The activity rate of catalase in figure 1 is calculated to be approximately 0.15mL/sec. The following figures show how this rate of reaction is affected by different external factors.
The results in figures 2 and 5 show an increase in either enzyme concentration or substrate concentration will increase the enzyme activity. In figure 2, the 0.75% enzyme concentration had the highest enzyme activity with a rate of 0.11mL/sec; whereas the…
Enzymes are protein molecules that occur in all living things on earth and enable chemical reactions. Enzymes not only provide an alternate pathway for a chemical reaction, with a lower activation energy, they also bring substrates together in an optimal orientation, thereby speeding up the rate of reaction (Slide Share 2016). In an enzyme catalyzed reaction, the substrate (reactant) binds to the active site and forms and intermediate substance known as the enzyme-substrate complex with the…
• To investigate the effects of on the rate of reaction of magnesium with different concentrations of Hydrochloric acid (HCl).
• To investigate the effects of different surface areas of magnesium in its rate of reaction with hydrochloric acid (HCl).
The rate in which reactions occur between chemicals, such as Magnesium and Hydrochloric Acid, are effected by four main factors. These factors are temperature, concentration, the presence of a catalyst and the surface area of…
The Reaction of a food dye with bleach
The overall purpose of the experiment was to determine the order in respect to the blue dye and the rate constant (K). With these found however, the overall rate law in the reaction between blue food coloring and the bleaching agent within commercial Clorox can be found.
The orders in a rate law equation represent the relationship between the concentration of a given element or molecule and the overall rate, for example, when a reaction in…
was to observe the organic displacement clock reaction and see how different properties - such as concentration and temperature - affect the reaction rate. This was to enhance understanding and gain knowledge of how certain properties affect reaction mechanisms and activation energies, and how acid-base equilibria behaves.
The data generally supported the hypothesis. It can be clearly seen that higher molarities of t-BuCl gave faster reaction rates, and it is an even clearer trend between the…
