dc.description.abstract | Generally, the only items of reference data with real economic impact are—except in a few instances—the basic values from which the standard enthalpy increment of reactions and the Gibbs energy of formation of the substances involved in the reaction. The energetic requirements of chemical processing mandate exact values here as well as for rather precise Gibbs energies needed for evaluation of equilibrium constants. Even here the contribution may lie less in the intrinsic value of that accuracy than in the implicit reliability and ready availability of the tables. CODATA's endeavors and scientific task groups dealing with fundamental constants, key values for thermodynamics, internationalization and systematization of thermodynamic tables to assist chemical industry are noted. Im allgemeinen kommt — von wenigen Ausnahmen abgesehen — von den Bezugsdaten nur denjenigen Grundwerten eine wirkliche ökonomische Bedeutung zu, aus denen die VerÄnderungen der Standardenthalpien der Reaktionen und die Gibbs'schen Bildungsenergien der an der Reaktion beteiligten Stoffe berechnet werden können. Die energetischen Erfordernisse der chemischen Verfahren müssen auf exakten Werten beruhen, ebenso wie die zur Berechnung von Gleichgewichtskonstanten benötigten Gibbs-Energien. Die Genauigkeit der individuellen Werte steht dabei weniger im Vordergrund als Vielmehr die ZuverlÄssigkeit und leichte ZugÄnglichkeit der Tabellen. Der Autor geht auf die Bestrebungen der CODATA (Committee on Data for Science and Technology) und derjenigen wissenschaftlichen Gruppen ein, die sich mit der Internationalisierung und Systematisierung der für die chemische Industrie zusammengestellten thermodynamischen Tabellen sowie mit grundlegenden Konstanten und thermodynamischen Werten befassen. жА ИсклУЧЕНИЕМ НЕкОт ОРых слУЧАЕВ, ОсНОВНы Е жНАЧЕНИь, Иж кОтОРых δ H v 0 И δ G f 0 Дль хИМИЧЕскИх РЕА кцИИ, ьВльУтсь тОлькО пУНктАМИ УпОМИНАЕМы х ДАННых пО ОтНОшЕНИУ РЕАльНОгО ЁкОНОМИЧЕ скОгО ВОжДЕИстВИь.
