The difference is that the first reaction happens in a few seconds, while the second occurs over several minutes. Explain why this so, based on what you know of chemical reactions and what you can see in these two reaction equations.
@whateversuper1987 In each of the three flasks the bromate and hydrogen ion concentrations were the same. The iodide (I-) concentration was different in each one. The one with the highest iodide concentration reacted fastest and the one with the lowest iodide concentration reacted slowest. This is because rate is proportional to concentration.
Thank you for the video. I just preformed the iodine clock experiment at school, this helps with the understanding behind it.

Consider the following two reactions:
5 Fe2+(aq) + MnO41-(aq) + 8 H1+(aq) 5 Fe3+(aq) + Mn2+(aq) + 4 H2 O(l)
2 MnO41-(aq) + 5 C2O42-(aq) + 16 H1+(aq) 2 Mn2+(aq) + CO2 (g) + 8 H2 O(l)
The difference is that the first reaction happens in a few seconds, while the second occurs over several minutes. Explain why this so, based on what you know of chemical reactions and what you can see in these two reaction equations.

were you using different solution to make it have rate reaction??

Instead of using BrO2- ions, we used H2SO4 and Iodate ions, which still reacted to produce Iodine. :o
