◆ getActivityConcentrations()

void getActivityConcentrations ( doublereal * c ) const

virtual

This method returns an array of generalized concentrations.

\( C^a_k\) are defined such that \( a_k = C^a_k / C^0_k, \) where \( C^0_k \) is a standard concentration defined below and \( a_k \) 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. Note that they may or may not have units of concentration — they might be partial pressures, mole fractions, or surface coverages, for example.

Parameters

c	Output array of generalized concentrations. The units depend upon the implementation of the reaction rate expressions within the phase.

Reimplemented from ThermoPhase.

◆ getStandardChemPotentials()

virtual

Get the array of chemical potentials at unit activity for the species at their standard states at the current T and P of the solution.

◆ standardConcentration()

doublereal standardConcentration ( size_t k = 0 ) const

virtual

Returns the standard Concentration in units of m3 kmol-1.

Return the standard concentration for the kth species.
The standard concentration \( C^0_k \) used to normalize the activity (i.e., generalized) concentration. In many cases, this quantity will be the same for all species in a phase - for example, for an ideal gas \( C^0_k = P/\hat R T \). For this reason, this method returns a single value, instead of an array. However, for phases in which the standard concentration is species-specific (e.g. surface species of different sizes), this method may be called with an optional parameter indicating the species.

Parameters

k	Optional parameter indicating the species. The default is to assume this refers to species 0.

Returns: Returns the standard concentration. The units are by definition dependent on the ThermoPhase and kinetics manager representation.
