This keyword data block is
used to define rate parameters in the style of Hermanska, Voigt, Marieni, Declercq, and Oelkers (2023). The
parameters can be used by the Basic function RATE_HERMANSKA to calculate
kinetic rates for any mineral in the data block. It is expected that the
function RATE_HERMANSKA will be used in rate definitions in the RATES
data block. RATE_HERMANSKA calculates rates without surface area or affinity
factors. These factors can be added in the RATES definition.

Eaa, n(H+), Neutral_log_K, Ab, Eab, Base_log_K, Ac, Eac, n(OH-)
Mineral name –Name of the mineral for which rates can be
calculated.
Acid_log_K –Nonzero indicates parameters for acid rate will be
used.
Aa—Rate constant for acid
rate.
Eaa—Activation energy for the
acid reaction.
n(H+)—Exponent of activity
of H+ in the acid rate equation.
Neutral_log_K— Nonzero
indicates parameters for the neutral rate will be used.
Ab—Rate constant for
neutral rate.
Eab—Activation energy for
the neutral reaction.
Base_log_K—Nonzero
indicates parameters for the base rate will be used.
Ac—Rate constant for base
rate.
Eac—Activation energy for
the base reaction.
n(OH-)—Exponent of activity
of OH- in the base rate equation.
