[CHM 112] Temperature Kinetics Lab Report

[Andrew J. Pounds]

Waht a yucky day outside -- a good day to knock out one of your lab
reports...

The temperature kinetics report is MUCH simpler than the concentration
kinetics lab report.  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 reactions.

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.

Watch the sign on the computed activation energy!


I will send out some help on the concentration kinetics lab writeup afte
group B completes the lab on Monday.
