For the dissociation constants 6j, 63, etc. holds : 



log C3 =r — y^ + ^2'>i + {% ^ — 1) , 



% ^, = -73 + ^^n + 2 (%/t: - 1) , 



etc., in which A^^j, A,!^, etc. represent the t^ariations of the entropj' 

 constant, divided by 11, viz. A^ij =1 (2 (i^j^ — (j^JJ : A^ A, 7^ =

If we now put all the quantities y and (^ = 0, which is allowed 

 for quasi association (otherwise we only think the teruis referrin-^ 



to it included in the dissociation constants, e.g., C/f'^ e~'''lf^'i =z 



= 6V, etc.), then for large volumes, where d\, i\, etc. \\'\\\\)q dight:

of which the first equation is identical with (2) of § 3. 



We further see, what we have already immediately put in our 

 abbreviated derivation, that really for very large volume .v^, a\, etc. 

 may be neglected by the side of i\, and that therefore the consider- 

 ation of the double molecules suffices with disregard of the numbers 

 of triple and multiple molecules. 



If we now again compare the equation (,•?) with {p-\-"/r"')iv — b')=RT 

 (the latter therefore without taking quasi association into account), 

 then (see also («) and (y) ) :
