The general form of an Arrhenius plot of ln(k) against 1/T is given by the equation below. The slope is equal to -Ea/R and the intercept at 1/T = 0 is equal to ln(A).
Where A is the pre-exponential factor (s-1), k has units of s-1, T is the temperature (kelvin), R is the gas constant (kJ K-1 mol-1), and Ea is the activation energy (kJ mol-1). To graph the variation of the rate constant K enter the parameters (i.e., A, Ea) and hit New Plot.
Up to 5 plots can be displayed at one time. The Clear button will remove all plots. To see the parameters
for each plot hit the Legend on/off button. The Redraw button will refresh the graph. This is useful when
the function domain (i.e., T ) has been changed. To see the value of each plot at a given point, move your cursor to the desired
location then click and hold.
