IODINE CLOCK METHOD COURSEWORK

In part B the activation energy was found to be 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. In conclusion, from part A the order of reaction of the iodate was found to be 2. Schoolworkhelper Editorial Team https: 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.

Schoolworkhelper Editorial Team https: 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. The experiment should have been done both ways to have the most accurate results. Also some solutions turned blue right away and others took a while so they could be seen by the human eye. The final rate law determined was:. 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.

Also some solutions turned blue right away and others took a while so they could be seen by the human eye. The slope represents the order of reaction with regards to the iodate, but the actual metnod is 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.

Please help us feed and educate children by uploading your old homework! The experiment should have been done both ways to have the most accurate results.

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. Some of the tubes may have gotten more stirred than others and this would have caused an inaccuracy in the times that were collected. It is assumed that the order of reaction with respect to the bisulfate is zero, thus n is zero. In cursework, from part A the order of reaction of the iodate was found to be 2.

Sample calculation for the rate constant, k for Rate 1 Again C1 stays the same for all calculations. This assumption courzework be further evaluated in the evaluation of the weaknesses and limitations. Schoolworkhelper Editorial Team cursework In part B the activation energy was found to be 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.

The order of reaction with respect to the iodate ion, mmust be determined for the following rate. In this lab, double replacement reactions between compounds were done in order to determine the equation and description of a new substance Iodine Clock Reaction Lab Answers. A limitation in part A would have been that the stirring would iodibe affected the time it took for the solution to turn blue. 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 final rate law determined was:.

Courseeork Clock Iodine lab Reaction. We will then predict from our results the correc 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.

All throughout the lab the assumption that is made throughout the lab is that the bisulfate ion has a reaction order of zero.

Better collection techniques such as spectrometry should have been used because then when ion changed colour it would be detected right away. 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. Also, when the tube was taken out the bath tub the room temperature immediately affected it, constantly changing the final courseork.
