[CHM 112] Help with Temperature Kinetics Lab

[Andrew J. Pounds]

The temperature kinetics report form is MUCH simpler than the 
concentration kinetics lab report form.  There are a few things that I 
want to point out that might be confusing.

1.  Make sure that ALL of your temperatures are in Kelvin.  You will 
lose MAJOR points if you don't do this.
2.  The rate is just the concentration of permanganate from the lab 
(0.0050) divided by 2 -- or 0.0025, divided by the time in seconds.  
This is the same for all of the reaction.

Make a plot of the natural log of the rate (on the Y axis) vs 1/T ( on 
the X axis).  Determine the slope of this line and then multiply that 
value by R (use the appropriate units, see the lab procedures) to 
determine the activation energy.

My head will explode if I see negative activation energies -- so don't 
even think about doing that (again -- MAJOR point killer).
