Physics · Atmospheric Chemistry
Peroxyacyl nitrates (PANs) are important in atmospheric chemistry because they:
- 1React rapidly to produce ozone directly in the urban environment without light
- 2Transport NOx to distant regions due to their thermal stability at high temperatures
- 3Dissociate slowly at lower temperatures, releasing radicals far from source regions✓
- 4Oxidize hydrocarbons during nighttime
Correct answer
Dissociate slowly at lower temperatures, releasing radicals far from source regions
