Question

The ionization energy of O₂ is 1205 kJ/mol: O₂ + hv → O₂⁺ + e^- The maximum wavelength of light capable of causing the ionization of O₂ is __________ nm.

Quizplus · Accepted Answer

The energy of a photon is given by E = hc/λ. Rearranging for wavelength, λ = hc/E. Using h = 6.626 × 10^-34 J·s, c = 3.00 × 10^8 m/s, and E = 1205 kJ/mol (converted to J/photon), the maximum wavelength is approximately 99.4 nm.

The Ionization Energy of O2 Is 1205 KJ/mol: O2

The Ionization Energy of O₂ Is 1205 KJ/mol: O₂
