Purpose:The Chapman Cycle Equilibrium Calculator solves for the equilibrium solution of the chemical reactions in the Chapman Cycle, assuming a solar flux equivalent to that at the top of the Earth's atmosphere. A Newton-Rhapson method is used to find the solution, which requires an initial guess as to the equilibrium solution.

Restrictions on Use: None

General Information:

1. Set the initial guesses of the concentration of Oxygen radicals, molecular oxygen, and Ozone in the atmosphere, as well as the concentration of the catalyst molecule.
2. Press Evaluate to calculate the equilibrium solution.
