Pcoeffs: Coefficients used for pressure-correcting the equilibrium constants

Description

Pressure corrections are based on the following equations:

lnKiPKi0=ΔViRT.P+0.5ΔKiRT.P2

with ΔVi=a0+a1T+a2T2 and ΔKi=b0+b1T+b2T2

The variables are:

  • K indicating the type of equilibrium constant

  • coefficient a0

  • coefficient a1

  • coefficient a2

  • coefficient b0

  • coefficient b1

  • coefficient b2

Usage

Pcoeffs

Arguments

Format

A data frame with 15 rows and 7 variables

Details

For Kb, to be consistent with Millero (1979) a2 was changed to -2.608e-3 instead of 2.608e-3 (value given in Millero, 1995) For Kw, coefficients are from Millero (1983).
