Standard further transformed Gibbs energy of formation

The amount of the oxygen component in the system is given by nc(O) = LN0(i)ni, where N0(i) is the number of oxygen atoms in reactant i. p 0(H2O) is the standard transformed chemical potential for H,0 at the specified pH and ionic strength. The standard further transformed Gibbs energy of formation of reactant i is given by...

Thus measurements of Af G ° and Af ° at a single temperature yield Af 5 ° at that temperature. If Af ° is known the standard further transformed Gibbs energy of formation can be expressed as a function of temperature, and then all the other thermodynamic properties can be calculated by taking partial derivatives of this function, as we have seen earlier in Chapter 4. 

This leads to the following equation for the standard further transformed Gibbs energy of formation of a reactant other than a... 

When standard further transformed Gibbs energies of formation Aj-G are used, the row for oxygen and the column for H2 O are omitted from the conservation matrix. 

It may appear puzzling that the summation in this equation does not involve the equilibrium mole fractions that appear in equation 14A-3. This is because the exponential terms in equation 14A-4 involve the standard further transformed Gibbs energies of formation rather than Af G,. The standard further transformed Gibbs energies of formation Af G, of the various forms are given by...
