一、化學反應如下 CH4(g)+CO2(g) → 2CO(g)+2H2(g) (此題21分) 附錄資料 CH4 (g) CO2 (g) A Hom -74.81 kJ/mole -393.509 kJ/mole Som AGºm 186.264 J/mole-K -50.72kJ/mole J/mole-K -394.359kJ/mole CO(g) -110.525kJ/mole J/mole-K -137.168kJ/mole H2(g) 0 kJ/mole J/mole-K 0 kJ/mole (1)利用附錄資料求上述反應在25℃時的△,Sm、ArGm。 (2)利用附錄資料的△G數據,求上述反應在25°C時的△Gm。 (3)在25℃時,若始態 CH4 (g)和CO2(g)的分壓均為150 kPa,末態 CO (g)和H2(g)的分壓均為50kPa,求反應的△rSm、A.Gm。

想請問一下第四和第五題☺️
