The diatomic molecule BrO undergoes two photodissociation pathways following laser excitation at 355 nm. Analysis of the reaction dynamics for the process that gives all ground-state products has generated a bond dissociation energy for BrO of 55.8 kcal mot. Given that the two processes that can occur are: 5) determine the maximum total translational energy that can be released for both processes shown above (in Joule units). (Hint: the ground state of Br is P2, and the energy difference between...
