hmm, the terrible thing is that you're a sophomore in college flexing your knowledge in chemistry that the atmosphere will spontaneously catch fire if it were 100% oxygen. When that really isn't how it works. this was my grad school text, this was my undergraduate text, and this is where I get my data for energies associated with reactions. Thermodynamics is used to tell you what will most likely happen in situations such as the one you so arrogantly talk about. You seem to have no background in it whatsoever.
