IODINE CLOCK METHOD COURSEWORK

Please help us feed and educate children by uploading your old homework! Iodine Clock Reaction Lab Answers. In conclusion, from part A the order of reaction of the iodate was found to be 2. 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, when the tube was taken out the bath tub the room temperature immediately affected it, constantly changing the final reaction. We will then predict from our results the correc Schoolworkhelper Editorial Team https:

Another relationship that can be seen between the rate constant and the temperature is that as the temperature increased the rate constant increased as well. The experiment should have been done both ways to have the most accurate results. Sample calculation for the rate constant, k for Rate 1 Again C1 stays the same for all calculations. Schoolworkhelper Editorial Team https: Also some solutions turned blue right away and others took a while so they could be seen by the human eye. 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.

It only takes seconds! A limitation in part A would clocl been that the stirring would have affected the time it took for the solution to turn blue. In this lab, double replacement reactions between compounds were done in order to determine the equation and description of a new substance The final rate law determined was:.

This assumption will be further evaluated in the evaluation of the weaknesses and limitations. Please help us feed and educate children by uploading your old homework! The order of reaction with respect to the iodate ion, mmust be determined for the following rate.

Also, when the tube was taken out the bath tub the room temperature immediately affected it, constantly changing the final reaction. 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 iodinee would have transferred heat to the solution.

In conclusion, from part A the order of reaction of the iodate was found to be 2. Instead of the foursework ion concentration being changed the concentration of the bisulfate could have been changed by making it the limiting reactant in the balanced equations. Schoolworkhelper Editorial Team https: We will then predict from our results the correc Answers Clock Iodine lab Reaction.

Iodine Clock Reaction Lab Answers. Some of the tubes may have gotten more stirred than others and this ikdine have caused an inaccuracy in the times that were collected. The slope represents the order of reaction with regards to the coursewotk, but the actual value is 2. All throughout the lab the assumption that is made throughout the lab is that the bisulfate ion has a reaction order of zero.

Sample calculation for the rate constant, k for Rate 1 Again C1 stays the same for all calculations. Better collection techniques such as spectrometry should have been used because then when ion changed colour it would be detected right away.

Another methd that can be seen between the rate constant and the temperature is that as the temperature increased the rate constant increased as well. 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.

It is assumed that the order of reaction with couesework to the bisulfate is zero, thus n is zero. 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. In part B the activation energy was found to be
