Calculation of Complex Equilibrium Relations Kaltcr Frey of Schtveizerhalle, Switzerland, h a s noted some errors in t h e article on “Calculation of Complex Equilibrium Relations” [Kandiner and Brinkley, 1x0. ENG.CHEM.,42, 850-5 (1950)l. T h e disorder arose from changing subscript notation while transcribing t h e illustrative example. We neglected inadvertently t o change the R’s, although t h e n’s were changed to conform with t h e notation employed i n the text. T h e following corrertions should be made in Table I on page 853:
K, = 1.93
X lo-‘
K g = 2.597 X K , = 3.448 x 10-3
Ks = 1.799 X lo-’ Ks = 2.155 X lo-‘ Kio = 3.846 X lo-‘
Frpy‘s correction to t h e equation for nlo is correct in principle and t h e equation on page 851 should read: 7llC
=
Kio (p/’n)-’
(n1)*(nJ-’
The defining equation (Equation 1) on page 851 should read:
