IODINE CLOCK METHOD COURSEWORK

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. Sample calculation for the rate constant, k for Rate 1 Again C1 stays the same for all calculations. Iodine Clock Reaction Lab Answers. 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. 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. It only takes seconds! The final rate law determined was:.

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. In this lab, double replacement reactions between compounds were done in order to determine the equation and description of a new substance A limitation in part A would have been that the stirring would have affected the time it took for the solution to turn blue. The order of reaction with respect to the iodate ion, m , must be determined for the following rate.

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. The experiment should have been done both ways to have the most accurate results. In conclusion, from part A the order of reaction of the iodate was found to be 2. Also because the assumption was made nethod the reaction order of the bisulfate was zero because it was constant throughout may have affected coock results as well.

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, but the actual value is 2. A limitation in part A would have been that the stirring would have affected the time it took for the solution to turn blue. All throughout the lab the assumption that is made throughout the lab is that the bisulfate ion has a reaction order coutsework zero. In part B the activation energy was found to be This assumption will be mdthod evaluated in the evaluation of the weaknesses and limitations.

Iodine Clock Reaction Lab Answers. Better collection techniques such as spectrometry should have been used because then when ion changed colour it would be detected right away. In this lab, double replacement reactions between compounds were done in order to determine the equation and description of a new substance Another relationship that can be seen between the rate constant and the temperature is that as the flock increased the rate constant increased as well.

Also, when the tube was taken out the bath tub the room temperature immediately affected mtehod, constantly changing the final reaction. 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. The order of reaction with respect to the iodate ion, mmust be determined for the following rate.

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! The final rate law determined was:.

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. Please help us feed and educate children by uploading your old homework! We will then predict from our results the correc Some of the tubes may have gotten more stirred than others and this would have caused an inaccuracy in the times that were collected.

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