In-Depth Information
some trial-and-error involved, still, given the complexity of the problem it is welcomed
among the Physical Chemistry and Reaction Engineering communities.
Figure 7.7
shows
the straight-line plot generated from the integral method. One can observe a pleasing straight
line passing through the data points on the (
t
,
y
) plane. The straight line is the best fit (from
the procedure discussed earlier):
y ¼ 0:006607 t
(7.44)
with a correlation coefficient of
R ¼ 0:99912 (7.45)
Since the regression is very good with the correlation coefficient close to unity and the data
scattering is minimal in
Fig. 7.7
, one has confidence that
Eqn (7.44)
can represent the trans-
formed data (
Table 7.4
). Therefore, the kinetic parameters are given by
