How does the energy generation of the CNO cycle compare to the PP chain regarding temperature sensitivity?
Answer
The CNO cycle energy production increases much more steeply with temperature ($T^{16}$ to $T^{20}$)
The PP chain reaction is relatively insensitive to temperature, relying on roughly the fourth power ($T^4$), whereas the CNO cycle's energy output increases dramatically faster with temperature, proportional to high powers like $T^{16}$ to $T^{20}$.
