Question

If two atoms are bonded with a bond energy of 87 kJ, what must be done to break the bond?

Answer 1

I would say the energy has to be decreased by 87 kj because the bonding is held together by 87 kj so removing that should prevent the bonding from taking place or reverse it I believe. In other words, a certain amount of energy is required to hold the bond together and in the absence of that energy, the bonding will not take place.
