Correction. The Preparation of Crystalline d-Talonic Acid

Abstract

The value of the 2 coefficient for ACp in Table III, p. 370, is incorrect because of an algebraic error in the summation and should be -14.73 X 10-7 instead of + 22.47 X 10-7. This produces a small change in the value of I, which now becomes -60.305 ± 0.091, and the standard free energy equation on this basis is AF°T = + 47,390 + 4.46 In -1.56 X 1( 3 2 + 2.455 X 10"7 3-60.305 .The free energy of formation of zinc oxide at 298 °K. is -75,720. Other values depending upon these figures will in consequence be subject to a small correction which, however, in general will be less than the experimental error of the determinations, and well within the figure of 300 calories probable error which we estimated in this work."1927, Volume 49 The Preparation of Crystalline d-Talonic Acid, by Oscar F.
