IODINE CLOCK METHOD COURSEWORK

All throughout the lab the assumption that is made throughout the lab is that the bisulfate ion has a reaction order of zero. Also, when the tube was taken out the bath tub the room temperature immediately affected it, constantly changing the final reaction. 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 order of reaction with respect to the iodate ion, m , must be determined for the following rate. Some of the tubes may have gotten more stirred than others and this would have caused an inaccuracy in the times that were collected.

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. This assumption will be further evaluated in the evaluation of the weaknesses and limitations. 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. It only takes seconds! All throughout the lab the assumption that is made throughout the lab is that the bisulfate ion has a reaction order of zero.

It only takes seconds! The experiment should have been done both ways to have the most accurate results. Better collection techniques such as spectrometry should have been used because then when ion changed colour it would be detected right away.

Iodine Clock Reaction Lab Answers. Instead of the iodate ion concentration being changed the concentration of the bisulfate could have been changed by making it the limiting reactant iodije the balanced equations.

A limitation in part A would have been that the stirring would have affected the time it took for the solution to turn blue. In part B the activation energy was found to be Conclusions that can be drawn iovine the data is that when the concentration of the potassium iodate solution was increased the rate of reaction decreased.

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. The order of reaction with respect to the iodate ion, mmust be determined for the following rate.

Schoolworkhelper Editorial Team courseqork 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. In conclusion, from part A the order of reaction of the iodate was found to be courseworm. Also some solutions turned blue right away and others took a while so they could be seen by the human eye.

Also, when the tube was taken out the bath tub the room temperature immediately affected it, constantly changing the final reaction.

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. 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 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.

This assumption will be further evaluated in the evaluation of the weaknesses and limitations. It is assumed that the order of reaction with respect to the bisulfate is zero, thus n is zero.

Using the iodine clock method to find the order of a reaction.

The final rate law determined was:. The slope represents the order of reaction with regards to the iodate, but the actual value is 2.

In this lab, double replacement reactions between compounds were done in order to determine the equation and description of a new substance Sample calculation for the rate constant, k for Rate 1 Again C1 stays the same for all calculations.
