The reaction is

displaymath57

Electrical work is non-PV work so we need a tex2html_wrap_inline61 . For this reaction

displaymath63

The reaction is just the formation reaction for liquid water so tex2html_wrap_inline65 . Pure water is produced so tex2html_wrap_inline67 . For the two gases, tex2html_wrap_inline69 so tex2html_wrap_inline71 and tex2html_wrap_inline73 . Therefore

eqnarray27
