According to IUPAC, standard state should be denoted with either a superscript circle (^circ) or a superscript Plimsoll symbol (^⦵+ xelatex compiler), not a zero; b. subscriptf("formation") should be upright, e.g.mathrmf; c.

This does steal a bit of the left margin, if that is not acceptable I think you would need to wrap the final term over two lines.

Note I moved the therefore back a bit so it's not so cramped (and so the display is a bit narrower and requires less overhang). Also never use \ before a display.

You need anothernonumberin the second iteration; the last equation isn't numbered in the original.

RegardingH_f(C_2H6)^0part: a. According to IUPAC, standard state should be denoted with either a superscript circle (^circ) or a superscript Plimsoll symbol (^⦵+ xelatex compiler), not a zero; b. subscriptf("formation") should be upright, e.g.mathrmf; c. It would be nice to fix typesetting for ethane (proper indices and upright font), e.g. withceC2H6. I also agree with @marmot that usingsiunitxwould make the answer look more professional.

Here, I use mathllap on the last line. But as you can see, there is still one remaining margin issue that you need to consider.
Also, the endalignat does not take an argument.

You could try to break up the remaining long line, but there may be other approaches, too...
I also made your kJ units upright, though, as marmot points out, the siunitx package is tailor made for applying units to quantities.

Other typography issues: Write phyical units (kJ) upright and separated by a space.
H_f(C_2H6)^0is wrong on several levels: subscript f should be upright, subscript formula should be upright (usece), superscript is not a 0, butcirc. IUPAC recommendation (Green Book) is to writeDelta_mathrmfH^circ (ceC2H6). Lastly, are you sure about your calculation? Unit of standard enthalpy is not kJ.– mhchem
