Model_chlorine.pol - This file includes all of the differential equations, rate coefficients, and initial concentrations of the chlorine model, for a time run of 1000 s. You will need to change the initial chlorine concentration to solve Part 2 of the Problems section.

Model.pol - This file includes all of the differential equations, rate coefficients, and initial concentrations of the chlorine + nitrogen oxides + bromine model, for a time run of 7000 s.

Equations_chlorine.pdf - This file includes a step-by-step procedure of the PSSH applied to the chlorine model, from the original algebraic expression of consumption/production to the final differential equations per species.
