- Arrhenius_plot abstract "An Arrhenius plot displays the logarithm of kinetic constants (, ordinate axis) plotted against inverse temperature (, abscissa). Arrhenius plots are often used to analyze the effect of temperature on the rates of chemical reactions. For a single rate-limited thermally activated process, an Arrhenius plot gives a straight line, from which the activation energy and the pre-exponential factor can both be determined.The Arrhenius equation can be given in the form:or alternativelyThe only difference is the energy units: the former form uses energy/mole, which is commonin chemistry, while the latter form uses energy directly, which is common in physics.The different units are accounted for in using either the gas constant or the Boltzmann constant .The former form can be written equivalently as:Where:= Rate constant= Pre-exponential factor= Activation energy= Gas constant= Absolute temperature, KWhen plotted in the manner described above, the value of the true y-intercept (at ) will correspond to , and the slope of the line will be equal to . The values of y-intercept and slope can be determined from the experimental points using simple linear regression with a spreadsheet.The pre-exponential factor, A, is an empirical constant of proportionality which has been estimated by various theories which take into account factors such as the frequency of collision between reacting particles, their relative orientation, and the entropy of activation. The expression represents the fraction of the molecules present in a gas which have energies equal to or in excess of activation energy at a particular temperature.".
