Chemistry Coursework Help

Im doing the clock readtion between bromide, bromate and hydrogen ions and have come across an issue
For clock reactions to work well the 'clock' part shoukd be 10-15% of the extent of the reaction
On one of the recommonded sources it suggests the concentrations of reactants to start with
The % extents seem to work for bromide and bromate however not for hydrogen ions

It suggests to use 1M sulfuric acid, if i were to use 0.01 mol/dm^3 sulfuric acid the percentage extent caluclaions work better

However, i was wondering whether by changing the concentration will it have any drastic impact on the reaction and its rate when i actually come to do the experiment?

Thanks in advance

Why don't you do a preliminary experiment to find out?
I wouldnt have any lab time in order to it unfortunately :frown:
