<font face="serif">For the concetration Kinetics Lab you will make
TWO graphs. Using the first set of data on the report form (the <img

src="cid:part1.07090706.09080102@mercer.edu" alt="$I^-$">
effect) you will plot the natural log of the rate on the Y axis
and the natural log of the <img style="vertical-align: middle"
src="cid:part1.07090706.09080102@mercer.edu" alt="$I^-$">
concentration on the X axis. Determine the slope of this line.
Then round the slope to the nearest whole number and that will be
the order with respect to <img style="vertical-align: middle"
src="cid:part1.07090706.09080102@mercer.edu" alt="$I^-$">. <br>
<br>
Remember -- the rate you are measuring is always for the PEROXIDE
so it is consistent between the first part of the lab and the
second part of the lab.<br>
<br>
For the second part of the lab repeat what you did in the first
part but now plot where you look at </font><font face="serif">the
natural log of the rate on the Y axis and the natural log of the <img
style="vertical-align: middle"
src="cid:part4.08060108.03090208@mercer.edu" alt="$H_2O_2$">
concentration on the X axis. Again determine the slope and then
convert this to a whole number to determine the order with respect
to peroxide.<br>
<br>
Now -- in the last part of the lab you need to calculate the rate
constant from all of your trials. This is pretty easy, take each
line of data and "solve for k"<br>

Whey you have just determined the values for the reaction orders.
You should get 8 values for k that should, theoretically, be close
to each other. Average all of them and report this value.<br>
