Answer:
The bond dissociation energy is the energy required to break a bond and form two atomic or molecular fragments, each with one electron of the original shared pair.
=> It is an endothermic process .
As , You have not mention the given values for Calculating Bond Energy of
HCl & HBr .
You can Use following Steps : -
To calculate bond energy : -
1 Add together the bond energies for all the bonds in the reactants – this is the 'energy in'.
2 .Add together the bond energies for all the bonds in the products – this is the 'energy out'.
3 . Then ,
Calculate the energy change
= energy in – energy out
= BOND ENERGY
