Which outcome lowers the initial reaction rate in atmospheric ozone formation when excess chlorine is present?

A)Chlorine radical chain termination
B)Increased UV radiation absorption
C)Enhanced heat dissipation ozone
D)Increased oxygen concentration locally

💡 Explanation

Chlorine radicals catalyze ozone breakdown via chain termination, thus decreasing initial ozone generation rate, because termination captures radicals, therefore slowing the overall reaction, rather than UV absorption which creates more, or concentration, which drives initial formation.
