Which mechanism causes increased oxidation rate in tungsten filaments?

A)Quantum electron tunneling through surface oxides
B)Increased thermal energy creating free radicals
C)Electromagnetic radiation excites oxygen molecules
D)Rapid surface area increase amplifies collisions

💡 Explanation

Quantum electron tunneling through an oxide layer causes increased passage events; because electrons tunnel, the oxide layer doesn't act as a perfect barrier. Therefore, oxidation happens faster rather than being limited by classic thermionic emission.
