Hi guys, i'm doing the iodine clock reaction for my advanced higher investigation. I understand the theory of kinetics and what not, but am extremely confused as to what to actually do in the procedure. The equipment I have been given is:
1% starch
0.001M ammonium molydbate-7-water
ammonium molydbate
Starch
10 Vol (3%) hydrogen peroxide
0.1 mol/l potassium iodide
1M sulphuric acid
0.1 M sodium thiosulfate
I have to do a variety of experiments which I think are:
1)Effect of hydrogen peroxide/ potassium iodide concentration on reaction rate
2) Effect of tempreature of reactants on reaction rate
3) Effect of catalyst (ammonium molybdate) on reaction rate
Are these right? And what volumes and concentrations do I use in the experiments ?I have also been told to mention the Arrhenius equations and activation energy.
Any help would be massively appreciated. Thanks so much guys!!
