In the second place we must prove the validity of this formula 
for reactions in dilute solution. For this purpose we introduce a new 
quantity, «’,, determined by the relation : 
WA ws RT gt 1 AAE ee Hr ek (5) 
So RT logn, is that part of the thermodynamic potential that 
is in connection with GrBBS’s paradox, and w'‚ the remaining part. 
Now as is known, the differential quotient of w, with respect to 
the concentrations ') remains finite, whereas that of the second part 
1) In contradiction to what is usual in the treatment of velocities of reaction, 
we define the concentrations here as molecular percentages of a certain substance in 
a definite mixture, and not as this quantity divided by the total volume. But it is 
clear that this does not affect the conclusions about the constancy of Ay and ky, 
as in every reaction in a dilute solution the change of volume during this reaction 
is disregarded.
