I'm doing the iodine clock with hydrogen peroxide. i know that in respect with I the order is first, in respect to H202 its first. However for H+ ions, im not sure whether its first or zero. ive read several different things, and now i'm just so confussssed

i got first order how can i tell from a half-life graph that its zeroth order? because for a first order, the half lives remain constant..
Is this not for the iodine clock, whereby you'd be timing how long it takes for a colour change to occur. and that would be time, t. then to calculate initial rate of reaction, you would simply use 1/t which is proportional to initial rate of reaction.
Then when you plot that on a graph you should get a constant horizontal line.
However for concentration against time graphs look at the image attached, it has examples shown.

ahh that means all my data and graphs are wrong for the H+, btw how do you know its zeroth order? and thank you so much, i actually understand it now <3

I only know its zeroth order from a task that I did in chemistry regarding this reaction.
Thank you guys <3 @grassgrazers have you done the coursework?
I've done the iodine clock using different chemicals, but a friend of mine did it with hydrogen peroxide. He experimentally found the order of H+ ions to be zeroth, and this was later confirmed by my teacher
