Q 1. If rate (d/t) is the dependent variable (y-axis) for this experiment, what is the independent variable (x-axis) for Activity 1? 2. Describe in detail the overall results of this experiment using numerical results (data that are numbers) with 5 sentences minimum. When explaining results numerical data should be given. To accomplish this, include the averages, rates (not time), and the difference between the slowest and the fastest rates (fastest rate- slowest rate). Is there a pattern you observed?3. Based on the information in Data Table 1, explain the relationship between percent concentration of catalase and reaction rate with a minimum of 3 sentences. Include the scientific reasoning for your results? Why did you see what you observed based on how an enzyme works?

1.The independent variable is the concentration level of hydrogen peroxide. This is because, as the concentration level increases, so does the reaction rate. 2.The results indicate that the average reaction time reduce by almost half the original reaction time with every increase in concentration of hydrogen peroxide. For instance, when the hydrogen peroxide concentration was increased from 25% to 50%, the reaction time reduced by 41.58%, while when the concentration of hydrogen peroxide was increased from 50% to 75% the reaction time reduced by 46.79%.
