<font face="serif">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.<br>
<br>
1. Make sure that ALL of your temperatures are in Kelvin. You
will lose MAJOR points if you don't do this.<br>
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.<br>
<br>
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.<br>
<br>
My head will explode if I see negative activation energies -- so
don't even think about doing that (again -- MAJOR point killer).<br>
