Third Law of Thermodynamics02:38

Third Law of Thermodynamics

21.7K
A pure, perfectly crystalline solid possessing no kinetic energy (that is, at a temperature of absolute zero, 0 K) may be described by a single microstate, as its purity, perfect crystallinity,and complete lack of motion means there is but one possible location for each identical atom or molecule comprising the crystal (W = 1). According to the Boltzmann equation, the entropy of this system is zero.

Electrophilic Addition of HX to 1,3-Butadiene: Thermodynamic vs Kinetic Control

3.6K
The addition of a hydrogen halide to 1,3-butadiene gives a mixture of 1,2- and 1,4-adducts. Since more substituted alkenes are more stable, the 1,4-adduct is expected to be the major product. However, the product distribution is strongly influenced by temperature; low temperature favors the 1,2-adduct, whereas the 1,4-adduct is predominant at high temperature.

Second Law of Thermodynamics

26.7K
In the quest to identify a property that may reliably predict the spontaneity of a process, a promising candidate has been identified: entropy. Processes that involve an increase in entropy of the system (ΔS > 0) are very often spontaneous; however, examples to the contrary are plentiful. By expanding consideration of entropy changes to include the surroundings, a significant conclusion regarding the relation between this property and spontaneity may be reached. In thermodynamic models, the...

Second Law of Thermodynamics

68.0K
The Second Law of Thermodynamics states that entropy, or the amount of disorder in a system, increases each time energy is transferred or transformed. Each energy transfer results in a certain amount of energy that is lost—usually in the form of heat—that increases the disorder of the surroundings. This can also be demonstrated in a classic food web. Herbivores harvest chemical energy from plants and release heat and carbon dioxide into the environment. Carnivores harvest the...

First Law of Thermodynamics

80.4K
The First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed. This can be demonstrated within a classic food web where light energy from the sun is harnessed as radiant energy by plants, converted into chemical energy, and stored as complex carbohydrates. The vegetation is then consumed by animals and during the digestion process, the sugars release energy as heat. The sugars also produce chemical energy that either gets used up doing work, stored in...

Area of Science:

  • Supramolecular Chemistry
  • Polymer Science
  • Materials Science

Background:

  • Supramolecular polymers exhibit complex self-assembly pathways, often involving hierarchical organization and non-equilibrium states.
  • Terminology describing these pathways, involved species, and their stability is frequently inconsistent and lacks clear experimental definitions.
  • Existing literature often uses varied terms for similar concepts, hindering a unified understanding of supramolecular polymerization.

Purpose of the Study:

  • To classify, differentiate, and correlate existing concepts related to complex supramolecular polymerization processes.
  • To provide a clear insight into the thermodynamic and kinetic aspects governing supramolecular self-assembly.
  • To establish a common language and framework for understanding and describing supramolecular polymer behavior.

Main Methods:

  • Literature review and analysis of recent high-quality publications in supramolecular polymer science.
  • Classification and correlation of diverse terminologies used to describe self-assembly pathways and species.
  • Synthesis of existing concepts to provide a generalized insight into thermodynamic and kinetic control.

Main Results:

  • Identification of common terms like 'hierarchical organization', 'out of equilibrium', and 'metastable species' in supramolecular polymer literature.
  • Demonstration of the lack of standardized definitions and experimental guidelines for many terms.
  • Correlation of thermodynamic stability and kinetic control in various self-assembly scenarios.

Conclusions:

  • A clear understanding and consistent application of terminology are crucial for advancing supramolecular polymer research.
  • This review provides a framework for interpreting the thermodynamic and kinetic aspects of complex self-assembly.
  • Improved comprehension will facilitate the rational design and development of novel functional supramolecular materials.
