I attached the full question.
We need to calculate the enthalpy change first:
Keep in mind this is the energy per mole, we need energy per atom:
We can see that this reaction needs the energy to get started (enthalpy change is positive).
The energy of a photon is given with this formula:
We need this photon to have the same energy (or higher) as our enthalpy change:
This wavelenght is clasified as near infrared.
