# Subroutines for calculating mineral dissolution rates from Palandri and Kharaka (2004) and Sverdrup et al. (2019).
# It facilitates to use the kinetic rates for various minerals compiled by these authors.
# Subroutines for calculating mineral dissolution rates from compilations by Palandri and Kharaka (2004), Sverdrup et al. (2019), and Hermanska et al., 2022, 2023.
# Numbers can be copied from the tables in the publications; when unavailable enter -30 for log_k, 0 for exponents and 1 for other parameters.
