When glucose is oxidized to carbon dioxide and water according to
the equationC6H12O6(s)+6O2(g) →6CO2(g) +6H2O(g) .Calorimetric measurement
give △U= -2810KJ and △S=182.4J at 25度C.How much of this energy change
can be extracted as (a)heat (b)work at this temperature? What are the values
of △A and △G?
请问各位大大应该要怎麽解,我似乎都找不到切入点。
在此先感谢回答的大大们,谢谢。

1F:→ messboy:HEAT: q=TdS -> W=U-q ->dA=dU-TdS 12/23 11:57
2F:→ messboy:G=H-TS <= H=U+PV ... 12/23 11:59
