I have a lab to do and I'm trying to find the initial rate. I know how to do the rate law and such but for some reason I'm not catching on for how to find the initial rate. Usually for the rate, they give you the I.R. Anyway, here's an attachment for you guys, if you need more info on how I got these numbers, just ask.

Btw if you're wondering about the numbers in the Time, runs 1 - 5 were for the change in Potassium Iodide concentration, while runs 6 - 9 were the change in Ammonium peroxydisulfate.
