Enthalpy?

[crayolé]

There are a few terms I've yet to get my head around

Imagine an enthalpy graph for a given endothermic reaction.

The products will have a higher enthalpy, does this equal higher bond energy = higher bond stability = higher bond strength?

[Mao]

higher bond energy = lower bond stability = lower bond strength.

This 'bond energy' is a potential energy. Imagine two bar magnets, to hold them at a close distance with the north poles facing each other, you need to put in some energy because they repel), this is the potential energy. If they are strong magnets you need to put in large amounts of energy, and their stability is low. Vice versa.
