KollegeApply · Accepted Answer

Ozone layer is depleted by NO. Explanation: 1. Chlorofluorocarbons (CFCs) and nitrogen oxides (NO, NO2) are the main culprits that destroy the ozone layer. 2. The following reaction occurs when ozone (O3) and nitric oxide (NO) interact in the stratosphere, causing ozone depletion: \ce{NO + O_3 -> NO_2 + O_2} 3. This process lowers ozone concentration, which aids in the ozone layer's thinning. 4. NO2, NO3, and N2O5 can also participate in atmospheric reactions, but NO plays the most direct role in ozone depletion.
