Thanks for the contribution @MichalKesl! Great job! Maybe we can use this opportunity to talk about how to test this function?

thermo_parity_plots.pdf Here is an example of the parity plot using this branch. One important comment on that is the parenthesis should be using \left(, \right), to make sure that they match the size of the \frac that is inside them. Also, I would have used \cdot to represent multiplication in the denominator of the entropy units, to differentiate the mol and K

Thanks! While we make the titles fancier, could you make H298 and S298 be something like \Delta H ^{298_K} _f}?

@MichalKesl, thanks, looking good. Could you please clean the commit message/description and rebase on main?
