So a continuing work with our main group chemistry, where we're looking at elements across the main groups that are periodic table looking at how they are able to react with one another. And we're expressing this in terms of, like that sort of summer dynamic work as well as chemical equations and how exactly electrons do transfer between species. So jumping straight into what we have here, we have equation for our reaction. We have an 02 oh, to that is in the solid state that generates on boat to, oh, solid state one half 02 in the Gezi estate. So now we're looking at Gibbs Energy of formations of Doubt. The G F is defined as Gibbs Energy off formation. That's our definition. So we have this valley for and 202 So for no Thio, it's negative. 379.79 We'll all starting material. It's negative. Full for nine 0.63 on then for oxygen. It's obviously zero for a pure state. So we have all some Dr G. F not off products, minus reactant. So then family 70 point five. Well, killer jewels, part mall. So the equation that we next need We know that Delta G no equals negative. R t l N k. So therefore, we can rearrange for Alan Kay. Well, im k Andi solve. Okay, so then what we get is K equal to four 0.3 to times 10 to the minus 13. So thermodynamic stability is when a species is at a lower energy state. The entropy change of the reaction from standard heat of formation. We can calculate that as well. So we do have Delta h of formation values. And so what we have is the sum Delta H formation off. Products minus are reactant. Delta H formation off. This reaction is 96 0.67 Keeler jewels. So we have a positive value, meaning that our products are at a higher energy than our reactant. And what I mean here is that if we go back to our reaction at the top, that are starting material is more stable than our product.
