At high temperature, methanol vapor decomposes according to the following equation:

           CH3OH(g)  -->  HCHO(g)  +  H2(g)       

      This reaction has DHo = 85.0 kJ, and DSo = 110 J/K

     Calculate DGo at 550oC and DG at the same temperature when the reaction is carried out under the following conditions: PH2 = 3.0 atm; PHCHO = 3.0 atm, and PCH3OH = 12 atm 

         (A) DGo = 24.5 kJ;           DG = 22.5 kJ

         (B) DGo = -5.5 kJ;            DG = -3.5 kJ

         (C) DGo = -5.5 kJ;            DG = -7.5 kJ

         (D) DGo = 175.5 kJ;          DG = 173.5 kJ
