Demonstration of the kinetics of series first order reactions. The concentrations of the three components A, B, and C are calculated for the system consisting of two sequential non reversible first order reactions during the specified time period, and the resulting concentrations can be displayed graphically.
In 1978, Omer Roucoux published this chemical jigsaw puzzle. It is available here in two parts, as a GIF and the original DrawFile version (for RISC OS), which you can download separately. Best hard copy results will be obtained from the original.
