How Does Temperature Affect The Rate Of Hydrogen Peroxide

Graph 4 shows a positive correlation between volume of oxygen and the increase of hydrogen peroxide; as the amount of substrate increases, the more oxygen is produced from the enzymatic reaction of hydrogen peroxide. For example, when five drops of hydrogen peroxide was added, it can be seen that 16.2mL of oxygen collected in the gas syringe, whilst when 15 drops were added, 96.4mL of oxygen was indicated, strongly supporting the original hypothesis, which was that as more hydrogen peroxide was added to the yeast, the higher the rate of reaction. Graph 5 further supports the original hypothesis, as it demonstrates the change the rate of reaction according increased volume of hydrogen peroxide, whereby the fastest rate of reaction occurred at the highest number of drops added to the solution.
The graph shows that there is a gradual increase from 0 drops to 10 drops of hydrogen peroxide, where the rate of reaction goes from 0cm3s-1 to 0.215cm3s-1. Following this, there is a rapid increase in the rate of reaction from 10 drops of hydrogen peroxide to 15 drops, where the rate changed from 0.215cm3s-1 to 0.803cm3s-1; an increase of nearly 4 times that occurred in a range of 5 drops, as opposed the 0.215 change occuring in a span of 10 drops, indicating that as hydrogen peroxide presence increased, rate of reaction increased rapidly. The results show support for the original hypothesis; therefore the hypothesis is accepted and it can be said that as substrate saturation increases, the rate of reaction also
