As seen in the figure, the experimental data can be
approximated reasonably well with a linear relationship. The rate constant k (the slope in Fig. 5) and the half-life degradation
time (t1/2 ¼ 0.693/k) were calculated from these data and
are summarized in Table 1, for the four initial concentrations
investigated. The errors given in Table 1 resulted from the
linear fit of the experimental data points.
