Varying The Rate Of Reaction
Given the data presented above, there are not clear conclusions that can be drawn. In Table 4, there is information regarding the effects of varying the concentration of a substrate, in this case the pea extract. To view the graphical representation, which more clearly displays the relationship, view Figure 2. The rate at which the reaction occurred for the 100% concentration is 1.45 mg/dL per minute. For the 50%, the rate was 3.05 mg/dL per minute, and for the 25%, the rate was 2.76 mg/dL per minute. As seen, the rate fluctuated from the lowest rate at 100% and the greatest rate occurring at 50%. As mentioned earlier, the Collision Theory states the rate of a chemical reaction is proportional to the number of collisions that occur. One way to increase the number of collisions is to increase the concentration, therefore proving that the data determine from this experiment is inaccurate. The expected result should have been as the

When looking at Table 5, when the temperature is at 40 °C, the rate of the reaction was 6.51 mg/dL. For 25 °C, the rate was 3.05 md/dL, and for the 10 °C, a rate of 1.77 mg/dL was found. This is consistent with what should occur, and what was predicted. This relationship is more clearly seen in figure 3. As temperature increases, the rate of the reaction should also increase due to the increase in the kinetic energy of the . Increasing the temperature increases the number of collisions between the enzyme and substrate per unit of time, therefore increasing the rate of the reaction. Although there is a clear increase in rate, there is not a consistent factor at which the temperature increases the rate. Raising the temperature from 10 °C to 25 °C, led to an increase factor of around 1.72, while increasing another 15 ° from 25 °C to 40 °C led to an increase factor of about only
