Configurational Entropy Revisited

Abstract: Entropy change is categorized in some prominent general chemistry textbooks as being either positional (configurational) or thermal. In those texts, the accompanying emphasis on the dispersal of matter—independent of energy considerations and thus in discord with kinetic molecular theory—is most troubling. This article shows that the variants of entropy can be treated from a unified viewpoint and argues that to decrease students' confusion about the nature of entropy change these variants of entropy should be … Show more

“…& The disorder metaphor emphasises spatial configuration of the constituent particles of a system, but tends to neglect the role of energy (Lambert 2002b(Lambert , 2007Alonso and Finn 1995;Brosseau and Viard 1992). & The messy room analogy and other examples, such as a particular poker hand, give a single snapshot view, rather than showing the large number of microstates, i.e.…”

“…A segunda lei analisa a espontaneidade das transformações e explica por que algumas reações ocorrem espontaneamente, enquanto outras não. A espontaneidade de uma reação tende a crescer com o aumento da entropia (S), a qual é tratada como uma medida da maior dispersão de energia de um sistema (ou sistema mais vizinhanças) [16]. A variação de entropia de um sistema pode ser calculada pela equação 2.…”

“…Differently, thermodynamic entropy is defined through the relation dS = δQ/T where δQ is the infinitesimal heat exchanged by the system with its environment at temperature T . However, it is strongly believed that configurational entropy and thermodynamical entropy should represent ultimately the same physical quantity in spite of their different expression [21]. Differently, in the non-extensive formalism, the equivalence between the configurational entropy and thermodynamical entropy is still an open question.…”
