← TechnologyWhich outcome directly results when halogenated refrigerant degrades via photolysis in the stratosphere?
A)Ozone depletion acceleration✓
B)Acid rain formation at surface
C)Increased greenhouse warming
D)Refrigerant flammability increase
💡 Explanation
When halogenated refrigerants reach the stratosphere, UV radiation causes photolysis because C-halogen bonds break. This releases halogen radicals which catalyze ozone destruction via chain reactions, accelerating ozone depletion. Ozone depletion acceleration directly follows; acid rain, warming, or flammability changes involve different chemical pathways.
