‎First appearance of all 4 papers constituting Planck's seminal papers on entropy carrying the general title ""On the principles of Increase of Entropy"" in which he applied the second law of thermodynamics to chemical problems.""His goal was, as he said in the first paper of the series, to carry further the ""grand generalization"" of Helmholtz, Josiah Willard Gibbs, and others: like the first principle of the mechanical heat theory, the second, the ""Carnot-Clausius"", principle applies not only to heat phenomena but to all kinds of physical and chemical phenomena"" and because the second principle applies not only to reversible processes but also to irreversible, or ""natural"", processes, it applies to all processes whatsoever...""(Jungnickel and McCormach ""Intellectual Mastery of Nature, vol. 2, pp. 52 ff.)What Einstein admired and called Planck's ""first great scientific discovery"" was the generality of its formulas which contain all that can be derived from pure thermodynamic principles. Einstein referred to the third paper in this series with the title ""Gesetze des Eintritts beliebiger thermodynamischer und chemischer Reactionen""Akademie Nos. 8,9,10 and 20.‎
