the hydrogen oxidation or water formation n= 2. The free enthalpies Gof water formation is either fG H 2O (g ) = 228:57 kJ=mol or fG H 2O l = 237:13 kJ=mol Therefore the corresponding EMFs are: E 0 g = fG H 2O (g) 2F = 1:184 V E l = fG H 2O (l) 2F = 1:229 V (1.1) These voltages are the maximum voltages which can (theoretically) be obtained from ...
