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? 請問各位大大應該要怎麼解,我似乎都找不到切入點。 在此先感謝回答的大大們,謝謝。 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.116.118.182
