Resumen
The photo-oxidation of n-butane and trans-but-2-ene is simulated under conditions of constant irradiation (normal incidence zero zenith angle) at sea level and at the altitude of Mexico City (2234 m). The object is to understand step by step the effect of changes in irradiation and atmospheric pressure on the production of ozone in a contaminated atmosphere, the individual and combined effects of irradiation and pressure were explored.
