An evaluation of the relationship between kinetic data collection of DTG curves and its corresponding R-square and activation energy values for kinetic plots

In this study the significance of data point collection on R-square values and activation energy values of resulting kinetic plots is explored. Several data collection sets were examined to observe this phenomena. These data sets were taken from DTG plots of benzophenone. Benzophenone undergoes a zero-order kinetics process as it evaporates. The maximum number of data points, which may be utilized to give an optimum R-square value of 0.9999, is established. This number is the optimum number of data points that should be collected to ensure a resulting linear kinetic plot. This is also the number of data points which will provide a more accurate activation energy value determination.
