C. Thermodynamic Relationships Involving the Equilibrium Constant1

1 For the limitations and for further explanation of these relationships, see, for example, K. Denbigh, The Principles of Chemical Equilibrium, 3rd ed. Cambridge: Cambridge University Press, 1971, p. 138.

For the gas-phase reaction

A+baBca+daD(2-2)

  1. The true (dimensionless) equilibrium constant

    RTInK = –ΔG

    K=aCc/aaDd/aaAaBb/a

    where ai is the activity of species i

    ai=fifi

    where

    fi = fugacity of species i

    fi = fugacity of species i at the standard state. For gases, the standard state is 1 bar, which is in the noise level of 1 atm, so we will use atm.

    ai=fifi=γiPi

    where γi is the activity coefficient

    K = True equilibrium constant

    Kγ Activity equilibrium constant

    Kp
