CHEMICAL KINETICS: THE IODINE CLOCK REACTION R. CABASAN[1] 1 DEPARTMENT OF FOOD SCIENCE AND NUTRITION, COLLEGE OF HOME ECONOMICS UNIVERSITY OF THE PHILIPPINES, DILIMAN, QUEZON CITY , PHILIPPINES DATE SUBMITTED: 27 FEBRUARY DATE PERFORMED: 11 FEBRUARY ABSTRACT The iodine clock reaction was used to examine the . Experiment 4: Kinetics of an Iodine Clock Reaction I. Introduction This experiment is designed to study the kinetics of a chemical reaction. The reaction involves the oxidation of iodide ions by bromate ions in the presence of acid. The objective of this lab is to determine. A Sample Lab Report The Iodine Clock Reaction Introduction: The factors that affect the rate of a chemical reaction are important to understand due to the importance of many such reactions to our health, well-being and comfort. It would be advantageous to slow down some of these reactions such as food spoilage and rust formations.



The order of reaction with respect to the iodate ion, mmust be determined for the following rate. It is assumed that the order of reaction with respect to the bisulfate is zero, thus n is zero. The slope represents the order of reaction with regards to the iodate, iodine clock reaction lab report, but the actual value is 2. Sample calculation for the rate constant, k for Rate 1 Again C1 stays the same for all calculations. In conclusion, iodine clock reaction lab report, from part A the order of reaction of the iodate was found to be 2.

The final rate law determined was:. In part B the activation energy was found to be Conclusions that can be drawn from the data is that when the concentration of the potassium iodate solution was increased the rate of reaction decreased. Another relationship that can be seen between the rate constant and the temperature is that as the temperature increased the rate iodine clock reaction lab report increased as well. Iodine clock reaction lab report throughout the lab the assumption that is made throughout the lab is that the bisulfate ion has a reaction order of zero.

This assumption will be further evaluated in the evaluation of the weaknesses and limitations. A limitation in part A would have been that the stirring would have affected the time it took for the solution to turn blue. Some of the tubes may have gotten more stirred than others and this would have caused an inaccuracy in the times that were collected. Also some solutions turned blue right away and others took a while so they could be seen by the human eye.

Better collection techniques such as spectrometry should have been used because then when ion changed colour it would be detected right away. As well another way that the procedure can be improved upon is to perform the lab like a titration lab using a burette, flask and the indicator. Also because the assumption was made that the reaction order of the bisulfate was zero because it was constant throughout may have affected the results as well. The experiment should have iodine clock reaction lab report done both ways to have the most accurate results.

Instead of the iodate ion concentration being changed the concentration of the bisulfate could have been changed by making it the limiting reactant in the balanced equations.

Lastly a limitation in part B is that a final temperature for the solution could not be measured because of all of the surrounding influences such as holding the tube would have transferred heat to the solution.

Also, when the tube was taken out the bath tub the room temperature immediately affected it, constantly changing the final reaction. Article last reviewed: St. Skip to content.
