does anyone know where i can find the order (zero, first, second) for the iodide ion?

Question

i am trying to find the rate constant k' for my experiment and can't come up with a whole number for my initial iodide concentration. the equation is
rate = k' [I-][H2o2]

and i've already found from my graph that H2O2 is first order.

anyone done this experiment before and have a value for iodide's order or even k'?

any help or explanations are much appreciated!

Answer 1

If H2O2 is first-order, I- must also be first order (since in the RDS (Rate-Determining-Step) of a reaction, only two particles can collide).
