O undergoes photochemical dissociation into one normal oxygen atom and one oxygen atom, 1.2 eV more energetic than normal. The dissociation of O into two normal atoms of oxygen requires 482.5 kJ/mol.

Question

O$_2$ undergoes photochemical dissociation into one normal oxygen atom and one oxygen atom, 1.2 eV more energetic than normal. The dissociation of O$_2$ into two normal atoms of oxygen requires 482.5 kJ/mol. The maximum wavelength effective for photochemical dissociation of O$_2$ is (1 eV = 96.5 kJ/mol)

Prashant Kotian · Accepted Answer

Correct answer: D. Dissociation energy into two normal atoms per molecule eV. Total required energy eV. The maximum wavelength nm. Therefore, correct answer is D.
