In the reaction:
PCl3 + Cl2 = PCl5
the bond energy for Cl-Cl is 243 kj/mol and for P-Cl it is 331 kj/mol
I know that bond energy for a reaction = sum of energy bonds broken - sum of energy of bonds formed
so how exactly would i find the bond energy?

Cl2 ===> 2Cl +243 kJ
PCl3 + 2Cl ===> PCl5 2 x -331 kJ = -662 kJ
So the total energy for the process is 243 - 662 = 419 kJ/mole. You broke a Cl-Cl bond and formed two new P-Cl bonds.
