Chemistry 2710 Spring 2000 Quiz 10 Solution
The Arrhenius parameters are obtained by plotting
vs T-1.
Our first task is therefore to calculate these quantities:
T-1 (
K-1) |
![$3.661\times 10^{-3}$](img2.gif) |
![$3.570\times
10^{-3}$](img3.gif) |
![$3.470\times 10^{-3}$](img4.gif) |
![$3.354\times 10^{-3}$](img5.gif) |
![$\ln k$](img1.gif) |
-10.117 |
-9.469 |
-8.956 |
-8.294 |
Here is the graph of the data:
The line has slope
and intercept 11.33. The
activation energy and preexponential factor are therefore
It should be noted that this reaction has unusually small activation
parameters.
