The general intent here was to enable calculating reaction enthalpies in the
Matlab toolbox, as part of the li-ion battery simulations in PR #563.
This required several changes:
- Create getDeltaEnthalpies.m in Matlab toolbox/@Kinetics, as well as similar
methods for Gibbs free energy and entropy of reaction
- Add kin_getDelta to kineticsmethods.cpp.
- Add getPartialMolarEnthalpies to metalPhase class (it returns all zeros).
Note that similar methods are not enabled for the corresponding
'Standard State' methods, for the time being. Mainly because it is
difficult for me to envision a significant use case, but also because of
some lingering confusion between 'standard' and 'reference' states in
Cantera's codebase.
