The energy required to separate a hydrogen molecule into its individual atoms is 104.2 kcal per mole

Question:

The energy required to separate a hydrogen molecule into its individual atoms is 104.2 kcal per mole of H2.

(a) If the dissociation energy for a single H2 molecule is provided by one photon, determine its frequency and wavelength.

(b) In what region of the electromagnetic spectrum does the photon found in part (a) lie? (Refer to the spectrum shown in Figure 25-12.)
