The code shows a 2D graph (can be called a 2D simulation) for Pseudo First Order kinetic and Linear Regression Analysis for Photocatalytic Degradation Model. It shows the prformance of a reaction based on the values of its concentration (not absorption) but it is related to absorption via the Beer Lambert's Law. (just notrepresented)

First-principles simulation of batch reactor kinetics (A→B→C) using Python & Scipy to optimize yield under thermal constraints.
