Two events are observed in a frame of reference S to occur at the same space point, with the second event occurring after a time
of 1.70 s . In a second frame S' moving relative to S, the second event is observed to occur after a time of 2.25 s . What is the difference between the positions of the two events as measured in S'?

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.
