We will then predict from our results the correc A limitation in part A would have been that the stirring would have affected the time it took for the solution to turn blue. 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. 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.

Iodine Clock Reaction Lab Answers. 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 some solutions turned blue right away and others took a while so they could be seen by the human eye. It is assumed that the order of reaction with respect to the bisulfate is zero, thus n is zero. Sample calculation for the rate constant, k for Rate 1 Again C1 stays the same for all calculations. Please help us feed and educate children by uploading your old homework! Some of the tubes may have gotten more stirred than others and this would have caused an inaccuracy in the times that were collected.

Iodine Clock Reaction Courseeork Answers. 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.

All throughout the lab the assumption that is made throughout the lab is that the bisulfate ion has a reaction order of zero. A limitation in part A would have been that the stirring would have affected the time it took for the solution to turn lcock. It only takes seconds! Also because the assumption was made that coureework reaction order of the bisulfate was zero because it was constant throughout may have affected the results as well.

In this lab, double replacement reactions between compounds were done in order to determine the equation and description of a new substance 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. Better collection techniques such as spectrometry should have been used because then when ion changed colour it would be detected right away.

Sample calculation for the rate constant, k for Rate 1 Again C1 stays the same for all calculations.

The final rate law determined was:. The order of reaction with respect to the iodate ion, mmust be determined for the following rate. Schoolworkhelper Editorial Team https: In part B the activation energy was found kodine be This assumption will be further evaluated in the evaluation of the weaknesses and limitations.

Also some solutions turned blue right away and others took a while so they could be seen by the human eye. 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. 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.

Some of the tubes may have gotten more stirred than others and this would have caused an inaccuracy in the times that were collected. In conclusion, from part A the order of reaction of the iodate was found to be 2.

The slope represents the order of reaction with regards to the iodate, but the actual value is 2. We will then predict from our results the correc It is assumed that the order of reaction with respect to the bisulfate is zero, thus n is zero. Also, when the tube was taken out the bath tub the room temperature immediately affected it, constantly changing the final reaction. Conclusions that can be drawn from the data is that when the concentration of the potassium iodate iodinne was increased the rate of reaction decreased.
