-
The thing is that PAN and its constituents/products form a steady-state at constant temperature, with PAN existing in balance with peroxyacetyl and NO2.

But this process is dominated by the behavior of peroxyacetyl radicals.

The asterisk * on the peroxyacetyl is one of the conventions used for indicating that it is a radical; it has an unpaired electron that plays well with others, especially if they also have an unpaired electron.

In the mid-1970s, PAN was discovered to thermally decompose, i.e. at elevated temperatures, it rapidly changed back to a peroxyacetyl radical and nitrogen dioxide.

By the same token, if something reduces the amount of peroxyacetyl, relative to other peroxy radicals, then PAN concentrations decline, NO2 comes back into the system, and ozone can increase.
