Answer:

The frequency of the photon that can dissociate dichlorine is 6.02×10¹⁴ Hz

Explanation:

The energy of a photon is given by the equation:

E=h·f

E=3.99×10⁻¹⁹ J/molecule

h (Planck's constant)=6.626×10⁻³⁴ m²·kg/s

∴ f=E/h

$f=\frac{3.99*10^{-19}J}{6.626*10^{-34} m²·kg/s}$ =6.02×10¹⁴ s⁻¹= 6.02×10¹⁴ Hz
