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
The true (dimensionless) equilibrium constant
RTInK = –ΔG
where ai is the activity of species i
where |
fi = fugacity of species i |
= 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. |
where γi is the activity coefficient
K = True equilibrium constant
Kγ Activity equilibrium constant
