Partial specific enthalpy

This means that the partial specific enthalpy of NaOH at infinite dilution ( at xN.OH 0) is aibirarily set equal to zero at 68(T). The graphical interpretation that the diagram is constructed in such a way that a tangent drawn to the isotherm at xNaOH = 0 intersects the xn oh = 1 ordinate (not shown) at an entl of zero. The selection of ff ttOH as zero at 68(°F) automatically fixes the values the enthalpy of NaOH in all other states.

This formulation follows directly from the definition of the partial specific enthalpies. The partial specific enthalpies have to be derived from a differentiation of the specific enthalpies with respect to the mole number.

In certain cases, the thermodynamic path can be made shorter. In particular in absence of chemical reactions among the components Q we can put directly = 0, more generally at least for any ( inert ) component not participating in any of the reactions. We can also select a basis of components such that any other component can be made up from the basis then the partial specific enthalpies equal zero for the basis, and if some remaining component Q arises by formal chemical reaction...
