According to the lab procedures...

" Thus a graph of ln (Rate) vs ln [ ] is a straight line which has a 
slope of n."

Now, you need to record the INITIAL CONCENTRATIONS IN THE FLASK (when 
all of the components are mixed together) for the I- and H2O2.

For the first graph you will plot the natural log of the rate on the 
Y-axis and the natural log of the concentration that is changing (I-) on 
the X-axis.

For the second graph you will plot the natural log of the rate on the 
Y-Axis and the natural log of the peroxide concentration on the X-axis.
