concentration in air to a sol-gel derived thin film (
Roy et al.,
2005
). Influence of temperature in
K: (a) 873 (b) 773 (c) 673 (d) Increase in the binding rate
coefficient, k with an increase in the fractal dimension, D
f
(e) Decrease in the binding rate
coefficient, k with an increase in the temperature (in
K).
Figure 10.3e
and
Table 10.3
show the increase in the binding rate coefficient,
k
, with an
increase in the temperature range 673-873
K. For the data shown in
Figure 10.3e
, the bind-
ing rate coefficient,
k
, is given by:
