Calculate the maximum nonexpansion work that can be gained from the oxidation of HCl (g) on a per gram basis under standard conditions. Please answer your question (unit kJ/g).

HCl (g) O2 (g) Cl2 (g) H2O (l)

fHo(kJmol-1)

-92.31 0 0 -285.83

So (JK-1mol-1)

186.91 205.14 223.07 69.91

fGo (kJmol-1)

-95.3 0 0 -237.15

I got until the point where you get kJ/m my answer was -93.1. But, from there I don't know what is the next step to convert to kJ/g. I tried and I got the answer -23.04 but that was wrong.

Please show me step by step, and result.

Thank you.

Answer #1

:-93.1 kJ/mole of Hce Imolence = 36.469 . -93.1 KJ_ - - 2.55 kJ/g + non-expansion work 36.469 HQ + 0, + Cl2 + H20 AHC+02 = 2H
