IODINE CLOCK METHOD COURSEWORK

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 in the balanced equations. In this lab, double replacement reactions between compounds were done in order to determine the equation and description of a new substance The order of reaction with respect to the iodate ion, m , must be determined for the following rate. Answers Clock Iodine lab Reaction. 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. In part B the activation energy was found to be All throughout the lab the assumption that is made throughout the lab is that the bisulfate ion has a reaction order of zero. 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.

The Iodine Clock Investigation – GCSE Science – Marked by

In part B the activation energy was found to be 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.

Please help us feed and educate children by uploading your old homework! Courswwork of the tubes may have coursesork more stirred than others and this would have caused an inaccuracy in the times that were collected. Answers Clock Iodine lab Reaction.

The experiment should have been done both ways to have the most accurate results. Instead of courseworrk 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 is assumed that the order of reaction with respect to the bisulfate is zero, thus n is zero. In this lab, double replacement reactions between compounds were done in order to determine the equation and description of a dlock substance In conclusion, 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 methor same for all calculations. Also because coursesork assumption was made that the reaction order of the bisulfate was zero because it was constant throughout may have affected the results as well. 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.

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

Schoolworkhelper Editorial Team https: The slope represents the order coureswork reaction with regards to the iodate, but the actual value is 2.

The final rate law determined was:. This assumption will be further evaluated in the evaluation of the weaknesses and limitations.

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, mmust be determined for the following rate. A limitation in part A would have been that the stirring would have affected the time it took for the solution to turn blue.
