Where is energy (kJ mol^-1), T is the temperature (kelvin), and R is the gas constant (J K^-1 mol^-1).

To graph the partition function enter the parameter (i.e., ) 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.
