Bond dissociation energy - Wikipedia, the free encyclopedia
I shouldn't have assumed you were looking at the same page based on what you were saying, but the information contained within tells you the same thing; the bond energy you're referring to is the average bond dissociation energy and has absolutely nothing to do with the activation energy required to break the bonds. It's just the average delta H. Since your quote contains that information as well it still proves me right. So, when is your trolling conspiracy BS going to come to an end? Saw ISS again last night, it was as beautiful as ever.
