K, first of all, cut down on the hyperbole. That's very, very tiresome.
Its not hyperbole. If you put these assumptions about how chemistry works into practice in an industrial setting, you will die, and that is no exaggeration. I mention this, because it is a clear way of telling whether the similar assumptions you make in your "statistical analysis" are at all accurate. They aren't, and so the statistic analysis you do based on your faulty assumptions is itself faulty...
Anyways, I don't always make posts that rebut in advance the likely responses. Perhaps I should have here. I would refer you to ionizing radiation in the atmosphere.
What? Weren't you saying that volcanoes "spew out oxygen"? Let me check... Yes, yes you were;
I do know enough about geochemistry to know that volcanoes (at least the ones that mankind has actual experience with) are spewing out mostly oxygen, and therefore volcanoes are a poor source of a purported substantial non-oxygen atmosphere.
Bold emphasis mine.
I am not an expert on atmospheric physics/chemistry, but it seems to me
Uh oh,
here we go again. You've got a
real high opinion of your ability to
guess at how chemistry works, True Blue.
that solar radiation ionizes compounds emitted by volcanoes, and at the end of the day, you're gonna end up with a lot of O2.
For your assumptions about the chemistry to be accurate, you have to know that the conditions of reaction favor your assumed outcome... as your "Golden Rules of O-Chem" link said; provide motive and opportunity.
Motive; the ionization energy of CO2* is 13.769 eV. Show that the ionization energy source you propose is sufficient to break this bond. I'll give you a hint, here; even UV-C at it's short end of 100 nm maxxes out at 12.4 eV, you're looking for more energy than that. The next shortest wavelength range of UV is UV-V (200 nm - 10 nm)
Opportunity; the ionization energy and the CO2 molecule should have a reasonable chance of interacting in large abundance (this is your proposed source for most ofour atmospheric oxygen, after all). Does the atmospheric strata that CO2 is found in (troposphere) experience the ionization energy at the intensity required to break up CO2 in any significant quantity? Or, is that ioinization energy depleted in the higher atmospheric strata before it has a chance to affect the CO2 in any appreciable amount? Here's your second hint, in the term UV-V above, the second 'V' is for 'Vacuum'... want to take a
guess at (or, look up on the Internet) UV-
V's relative abundance in an atmosphere?
* For simplicity, I picked one volcanic gas with atomic oxygen contained therein. You could do this same exercise with each atomic oxygen-containing gas, but I somehow doubt you'd be so inclined...
