dissociation field ?!? The average distance between the atomic components of a simple molecule is of the order of a few Angström. Estimate the magnitude of the field necessary to dissociate a molecule of [itex]N_2[/itex]. With no other information, is it possible to solve this ?!? We have a little document that talks about the atmosphere as an electrical circuit and it explains that lightning happens because the electric field dissociate molecules and then, blahblahblah, but that is IT.
