A simple thermodynamic model for a bulk phase, assuming a lattice of solid atoms.
The bulk consists of a matrix of equivalent sites whose molar density does not vary with temperature or pressure. The thermodynamics obeys the ideal solution laws. The phase and the pure species phases which comprise the standard states of the species are assumed to have zero volume expansivity and zero isothermal compressibility.
The density of matrix sites is given by the variable \( C_o \), which has SI units of kmol m-3.
It is assumed that the reference state thermodynamics may be obtained by a pointer to a populated species thermodynamic property manager class (see ThermoPhase::m_spthermo). However, how to relate pressure changes to the reference state thermodynamics is within this class.
Pressure is defined as an independent variable in this phase. However, it has no effect on any quantities, as the molar concentration is a constant.
The standard state enthalpy function is given by the following relation, which has a weak dependence on the system pressure, \( P \).
\[ h^o_k(T,P) = h^{ref}_k(T) + \left( \frac{P - P_{ref}}{C_o} \right) \]
For an incompressible substance, the molar internal energy is independent of pressure. Since the thermodynamic properties are specified by giving the standard-state enthalpy, the term \( \frac{P_{ref}}{C_o} \) is subtracted from the specified reference molar enthalpy to compute the standard state molar internal energy:
\[ u^o_k(T,P) = h^{ref}_k(T) - \frac{P_{ref}}{C_o} \]
The standard state heat capacity, internal energy, and entropy are independent of pressure. The standard state Gibbs free energy is obtained from the enthalpy and entropy functions.
The standard state molar volume is independent of temperature, pressure, and species identity:
\[ V^o_k(T,P) = \frac{1.0}{C_o} \]
The activity of species \( k \) defined in the phase, \( a_k \), is given by the ideal solution law:
\[ a_k = X_k , \]
where \( X_k \) is the mole fraction of species k. The chemical potential for species k is equal to
\[ \mu_k(T,P) = \mu^o_k(T, P) + R T \ln X_k \]
The partial molar entropy for species k is given by the following relation,
\[ \tilde{s}_k(T,P) = s^o_k(T,P) - R \ln X_k = s^{ref}_k(T) - R \ln X_k \]
The partial molar enthalpy for species k is
\[ \tilde{h}_k(T,P) = h^o_k(T,P) = h^{ref}_k(T) + \left( \frac{P - P_{ref}}{C_o} \right) \]
The partial molar Internal Energy for species k is
\[ \tilde{u}_k(T,P) = u^o_k(T,P) = u^{ref}_k(T) \]
The partial molar Heat Capacity for species k is
\[ \tilde{Cp}_k(T,P) = Cp^o_k(T,P) = Cp^{ref}_k(T) \]
The partial molar volume is independent of temperature, pressure, and species identity:
\[ \tilde{V}_k(T,P) = V^o_k(T,P) = \frac{1.0}{C_o} \]
It is assumed that the reference state thermodynamics may be obtained by a pointer to a populated species thermodynamic property manager class (see ThermoPhase::m_spthermo). How to relate pressure changes to the reference state thermodynamics is resolved at this level.
Pressure is defined as an independent variable in this phase. However, it only has a weak dependence on the enthalpy, and doesn't effect the molar concentration.
\( C^a_k \) are defined such that \( C^a_k = a_k = X_k \). \( C^s_k \), the standard concentration, is defined to be equal to one. \( a_k \) are activities used in the thermodynamic functions. These activity (or generalized) concentrations are used by kinetics manager classes to compute the forward and reverse rates of elementary reactions. The activity concentration, \( C^a_k \), is given by the following expression.
\[ C^a_k = C^s_k X_k = X_k \]
The standard concentration for species k is identically one
\[ C^s_k = C^s = 1.0 \]
For example, a bulk-phase binary gas reaction between species j and k, producing a new species l would have the following equation for its rate of progress variable, \( R^1 \), which has units of kmol m-3 s-1.
\[ R^1 = k^1 C_j^a C_k^a = k^1 X_j X_k \]
The reverse rate constant can then be obtained from the law of microscopic reversibility and the equilibrium expression for the system.
\[ \frac{X_j X_k}{ X_l} = K_a^{o,1} = \exp(\frac{\mu^o_l - \mu^o_j - \mu^o_k}{R T} ) \]
\( K_a^{o,1} \) is the dimensionless form of the equilibrium constant, associated with the pressure dependent standard states \( \mu^o_l(T,P) \) and their associated activities, \( a_l \), repeated here:
\[ \mu_l(T,P) = \mu^o_l(T, P) + R T \ln a_l \]
The concentration equilibrium constant, \( K_c \), may be obtained by changing over to activity concentrations. When this is done:
\[ \frac{C^a_j C^a_k}{ C^a_l} = C^o K_a^{o,1} = K_c^1 = \exp(\frac{\mu^{o}_l - \mu^{o}_j - \mu^{o}_k}{R T} ) \]
Kinetics managers will calculate the concentration equilibrium constant, \( K_c \), using the second and third part of the above expression as a definition for the concentration equilibrium constant.

Derived classes which do override this function should call their parent class's implementation of this function as their last action.

Apply changes to the state which are needed after the composition changes.
This function is called after any call to setMassFractions(), setMoleFractions(), or similar. For phases which need to execute a callback after any change to the composition, it should be done by overriding this function rather than overriding all of the composition- setting functions. Derived class implementations of compositionChanged() should call the parent class method as well.
Reimplemented from Phase.

Update the species reference state thermodynamic functions.
The polynomials for the standard state functions are only reevaluated if the temperature has changed.

The current pressure.
Since the density isn't a function of pressure, but only of the mole fractions, we need to independently specify the pressure. The density variable which is inherited as part of the State class, m_dens, is always kept current whenever T, P, or X[] change.
