LLNL_AQUEOUS_MODEL_PARAMETERS

[Pak]

Probably a dumb question although it makes me wonder, if a database contains the LLNL_AQUEOUS_MODEL_PARAMETERS datablock. Does it mean that all the activities of the species are going to be calculated using the Lawrence Livermore National Laboratory aqueous model (Daveler and Wolery, 1992)?

Thank you

The LLNL_AQUEOUS_MODEL_PARAMETERS provides parameters to calculate dh_a, dh_b, bdot, and CO2 bdot (uncharged species Setchenow coefficient). However, these parameters are not used unless an aqueous species is defined (SOLUTION_SPECIES) with -llnl_gamma or -CO2_llnl_gamma.
