Useful resource for rate parameters

Palandri, J.L., and Kharaka, Y.K. (2004). A compilation of rate parameters of water-mineral interaction kinetics for application to geochemical modeling.

From the USGS, can be found here:

http://pubs.usgs.gov/of/2004/1068/pdf/OFR_2004_1068.pdf

Document includes dissolution rate parameters (log k) for a wide range of minerals.

A database of dissolution and precipitation rates for clay-rocks minerals

[taa18]

The database provided by Palandri and Kharaka, they suggested raising activity of H+ to a negative power instead of using a positive power fro the activity of OH-. I could not implement the negative power of H+ in phreeqc, anybody else facing the same issue?

PHREEQC has the PHREEQC_RATES.DAT database since version 3.8. It contains the kinetic rate parameters in the tabular format copied directly from the compilations by Palandri and Kharaka (2004), Sverdrup et al. (2019) and Hermansk? et al. (2022, 2023). It is no longer necessary to write a detailed BASIC program for these rates, which greatly facilitates to intercompare the various rates in a kinetic model.

For explanation and examples see:
hydrochemistry.eu/exmpls/kin_silicates.html

Rate parameter blocks were added to PHREEQC.DAT:
RATE_PARAMETERS_PK
RATE_PARAMETERS_SVD
RATE_PARAMETERS_HERMANSKA
Missing PHASES were copied from ThermoddemV1.10_15Dec2020.dat
