Rate Of Reaction Lab

Decent Essays
The results and that were obtained in this lab are fairly reliable and reasonable. This is because if you refer back to Graph 1.1 for example it is clear that there is a relative and steady increase in the rate of reaction as the concentration of catalase was increased. Although in part A, the results were fairly reliable and they clearly show the average increase in part B, one can see that the results that were obtained during the experiment were outliers of each other. Looking back at the table from part B when the 80% concentration of catalase was placed into the 3% Hydrogen Peroxide + 10% Copper II Sulphate the results of time it took for the filter disk to reach the top seemed to be unreasonable. In trial 1 and 2 the time that was recorded…show more content…
In the comparison of the two reactions occurring with the 80% in part A and B it makes sense that the rate of reaction in part B is slower because of the non-competitive inhibitor that was acting upon the catalase. But, the rate of reaction seems to be too low for the result too be realistic indicating a human error and causing it to be slightly unreliable. Failing to change the hydrogen peroxide from part A to a new solution in part B may be an example of human error. An experimental error that may have affected the results obtained during the experiment was the labs failure to mention to mix the two substances, hydrogen peroxide and copper II sulphate in part B. Failure to mention this simple instruction may have led to the outliers in time retrieved in part B for the experiment. In the first trial when the filter timed out at 240 seconds at the bottom of the beaker, it may have been caused by the un-dissolved copper II sulphate still at the bottom of the beaker. Another experimental error was that during the experiment it was stated that if one was able to hurry and do the first two trials quickly then there may be time for a third
