Hi yall! Does anyone know how one can solve kinetíc energy of H-atom if the dissociation energy and the wavelenght of photons are known when HBr-molecules are photodissociated? Tricky... :cry:

I'll take a stab at this. You know by Einstein's equation E=hv=hc/Lamda.


E=dissociation energy+kinetic energy. You can find E and you are given dissociation energy, solve for kinetic energy.


Again, I am not 100% sure if this is correct.

At what temperature and pressure ?
