Question

The energy required to split apart dichlorine according to the equation is 3.99 × 10-19 J/molecule. Cl2(g) → 2Cl(g) Calculate the frequency (Hz) of the photon that can dissociate dichlorine. Express answer in scientific notation.

Answer 1

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

Step-by-step 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=(3.99*10^(-19)J)/(6.626*10^(-34) m²·kg/s)`=6.02×10¹⁴ s⁻¹= 6.02×10¹⁴ Hz
