Create a graph using a graphing program such as Excel or you can had draw your graph. Insert the graph of Activity 1 data here.
Based on the information in Data Table 1, explain the relationship between percent concentration of catalase and reaction rate.
Base the information from Table 1, the response rate increments as the concentration of the chemical increments. From the testes it has been appeared that the coordinate relationship is watched when the concentration of hydrogen peroxide is more prominent than 0.0987%.
Using the graph, predict the rate if catalase concentrations are 10%, 60% and 85%.

Create a graph using a graphing program such as Excel or you can had draw your graph. Insert the graph of Activity 2 data here.
Interpret the graph for Activity 2. Is there an optimum temperature for catalase that makes it the most productive in terms of reaction rate? At what temperature does the rate decrease? Explain why.
