# For the reaction aA + bB = cC + dD,
# with delta_v = c*Vm(C) + d*Vm(D) - a*Vm(A) - b*Vm(B),
# PHREEQC adds the pressure term to log_k: -= delta_v * (P - 1) / (2.3RT).
# Vm(A) is volume of A, cm3/mol, P is pressure, atm, R is the gas constant, T is Kelvin.
# Gas-pressures and fugacity coefficients are calculated with Peng-Robinson's EOS.
# Binary interaction coefficients from Soreide and Whitson, 1992, FPE 77, 217 are
# hard-coded in calc_PR():

# H2O 0.49 0.19 0.19 0.49
# =============================================================================================
# The molar volumes of solids are entered with
# -Vm vm cm3/mol
# vm is the molar volume, cm3/mol (default), but dm3/mol and m3/mol are permitted.
# Data for minerals' vm (= MW (g/mol) / rho (g/cm3)) are defined using rho from
# Deer, Howie and Zussman, The rock-forming minerals, Longman.
# --------------------
# Temperature- and pressure-dependent volumina of aqueous species are calculated with a Redlich-
# type equation (cf. Redlich and Meyer, Chem. Rev. 64, 221), from parameters entered with
# -Vm a1 a2 a3 a4 W a0 i1 i2 i3 i4
# The volume (cm3/mol) is
# Vm(T, pb, I) = 41.84 * (a1 * 0.1 + a2 * 100 / (2600 + pb) + a3 / (T - 228) +
# a4 * 1e4 / (2600 + pb) / (T - 228) - W * QBrn)
# + z^2 / 2 * Av * f(I^0.5)
# + (i1 + i2 / (T - 228) + i3 * (T - 228)) * I^i4
# Volumina at I = 0 are obtained using supcrt92 formulas (Johnson et al., 1992, CG 18, 899).
# 41.84 transforms cal/bar/mol into cm3/mol.
# pb is pressure in bar.
# W * QBrn is the energy of solvation, calculated from W and the pressure dependence of the
# Born equation.
# z is charge of the solute species.
# Av is the Debye-Hückel limiting slope.
# a0 is the ion-size parameter in the extended Debye-Hückel equation:
# f(I^0.5) = I^0.5) / (1 + a0 * DH_B * I^0.5),
# a0 = -gamma x for cations, = 0 for anions.
