The approach to equilibrium of a reaction that is first-order is given by
Where A0, is initial concentration of reactant A (mol L-1), t is time (s), and k1 and k2 are rate constants (s-1).
To graph the concentration of the reactants enter the parameters (i.e., A0, k1, k2) and hit New Plot.
Up to 3 plots pairs 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.
