If 836 kJ of energy is required to break the bond, then 836 kJ of energy is also required to form the bond.
The bond energy of a compound is defined as the energy required to break the bond between two atoms in a compound. We must note that the bond energy is always endothermic because because energy is taken in to break bonds.
The amount of energy required to break a bond is the same amount of energy required to form the bond. Hence if 836 kJ of energy is required to break the bond, then 836 kJ of energy is also required to form the bond.
