The relations were obtained between the thermodynamically consistent activity coefficient of associating component and the activity coefficient calculated irrespective of the association in the vapour phase. The analysis is limited to binary systems with one associating component and is given for the two cases: (a) the associating component dimerizes only, (b) the associating component forms, in addition to a dimer, one higher associate, too.
