Atomic Interaction Energy Graph
« on: March 20, 2019, 02:09:44 AM »
Im confused a bit about this question, what value is it referring to?

"the distance between nuclei is at the most likely value" = "nuclei are separated by the most likely distance" = "nuclei are at the most likely distance"

Is that answer correct then for e)?

The question refers explicitly to the distance e.

"Most likely distance" supposes implicitly that the molecules are formed and don't vibrate too much. At 3000K it wouldn't be the case.

So what is the most likely distance at e)?

The diagram is about nuclei separation, it has little to do with electron separation. Once electrons are close enough to overlap and form bonds they become indistinguishable, and discussing electron distance from each other becomes a bit meaningless.

1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.

Ah so the distance between nuclei would be the most likely value then?
