First order parallel reaction in PFR

A typical chemical engineering example of a first-order parallel reaction is simulated here. A GUI is also created to help in visualization.

A GUI for a typical first-order parallel chemical reaction in PFR (A----->B--->C) is simulated here. The GUI contains two sliders for changing the values of rate constants k1 and k2. GUI also contains options to enter the values for the initial concentration of species A and also the residence time of PFR. The concentration profile of species A, B, and C as a function of time spent in PFR can be visualized in the provided plot.
