I want to know how to draw the graph and the answer to these following questions for part 1 by what rate your [ ] decrease when you halfed the [kio3]? Why this occurred
b) what does the slope of the graph gives you
For part 2
Graph, and answerto the following for every 10C increase rate of rxn double is this statement true about your reaction

The thing is that I don't understand what you are saying.

what rate your [ ] decrease when you halfed the [kio3]? why this occured

What does that mean? What reaction occurred? What are you investigating?:confused:

There are several "iodine clock" reactions. '

Iodine clock reaction - Wikipedia, the free encyclopedia

You must be doing the "Iodate" version

In this protocol, iodide ion is generated by the following slow reaction between the iodate and bisulfite:







The first reaction is the rate-determining step, therefore the kinetics are determined by that reaction. I think that this would, therefore, be the rate equation, but I don't have time to verify it.



Here's a link on the kinetics.

Please explain your questions. You need to specify what graph you are talking about.

What is th epurpose of idodin clock reaction

[Unknown008]

Well, it can be used to determine the order of reaction with respect to the reactants used.
