    Rates of Chemical Reaction II Pre-Lab Summary: First we will set up the experiment as shown in Figure 2‚ and then we will fill the trough with room temperature water and record the temperature and we will also add the room temperature water to the buret until it is about 10ml from the top. If there are no leaks in the apparatus‚ we will add 10ml of KI to 15ml of distilled water in a 125ml flask. We will swirl the flask so that it achieves room temperature‚ then we will add 5ml of H2O2 and quickly

    catalyst in chemical reactions. Catalyst are used to increase the rate of a chemical reaction. In this study‚ we performed two different experiments that investigated the effect of varying substrate concentration‚ and the effect of temperature on the rate of Enzyme-Catalase reaction. In experiment one (i.e. the effect of varying substrate concentration on the rate of enzyme-catalase reaction) we tested the hypothesis HA as substrate concentration increases‚ so will reaction rate until all active sites

    From the graphs‚ it is evident that an increase in both catalase concentration and substrate concentration resulted in a higher rate of reaction or‚ as observed in the kPa graphs‚ a higher volume of O2(g) formed at the end of the 5 minute trial. Interestingly‚ it should also be noted‚ as it was mentioned in the Figure 2‚ that the trend for the 6mL of 3% H2O2(aq) was more of a linear trend than an exponential decay‚ steadily rising until the end of the 5 minute trial. From this‚ it can be inferred

    produced in an enzyme- catalase experiment. In the experiment we used liver extract as a catalase and created a chemical reaction within a reaction chamber between the catalase and hydrogen peroxide as well as three different controlled temperatures. In the procedure below there will be a step by step process as to how the experiment was created. As a result we found that the higher the temperature in the water bath the more oxygen will be produced and “rejected” from the reaction chamber. In conclusion

    there are many factors that will affect it’s rate. The rate of diffusion will vary depending on the size of the particle. For example‚ a smaller particle will move faster than a large molecule at a given temperature . During reactions‚ when there is more energy‚ the reaction will take place at a faster rate. An increase in temperature will result in and increase in the amount of energy available‚ therefore the particle will move faster and the rate of diffusion will increase. Another factor affecting

    This section analyzes and presents the results of the two trials conducted‚ including the trial in which Hydrogen peroxide(H2O2) was denatured by a cold catalase solution and the other in which the Hydrogen peroxide(H2O2) was denatured by a hot catalase solution. The experiment conducted displayed signs of experimental error as there were many situations in which the materials provided could have faulted. Theoretically speaking‚ from the inconsistent values provided for the pH levels‚ a possible

    to maintain the internal environment [2]. Hydrogen peroxide is an oxidizing agent that can be decomposed by catalase [11]‚ the liver is able to decompose hydrogen peroxide enzymatically because it contains catalase [12]. The reaction rate of an enzyme catalysed reaction under the effect of changes in temperature was tested in this experiment. It was hypothesised that the fastest reaction rate would occur a 37 degrees Celsius. Liver and hydrogen peroxide were placed into 4 different test tubes‚ all

    Determination of Rate and Order of a Reaction Results This experiment used a spectrometer to find the wavelength with maximum absorbance in a green food coloring solution. For this particular solution the wavelength was 629.7 nm. The system was then calibrated to that and was set to measure the food coloring and bleach solution. The measured visible light absorbance of the mixed solution was collected over a time of 200 seconds and eight points were then selected and placed into the Absorbance
