Re: [Phys-L] Energy & Bonds



How do I reconcile this with U=kqq/r ?
Isn't r getting smaller as they approach and bond? Then U is getting larger.

What is wrong with my model here?

Hi Paul

In your terms

The products are more bound because they must be more bound and have LESS potential energy

i.e. they require more energy to disrupt the bonds as there is stronger binding

Best wishes

Hi.
I am more aware of my conceptual shortcomings after the conversation about energy, reactions, and misconceptions.
I would appreciate clarification from the group on:
How do we reconcile the traditional Exothermic & Endothermic graphs of Energy vs reaction process with the fact that the products must be more bound and have greater potential energy? Typically the endo / exo graphs show (for an exothermic reaction) that the reactants have more energy than the products.

I may have more follow up questions.
Thanks.
Paul.
