Thermodynamics and the Free Energy of Chemical Substances

Target entity: Thermodynamics and the Free Energy of Chemical Substances
Context triple: [Gilbert N. Lewis, publication, Thermodynamics and the Free Energy of Chemical Substances]

• A. On the Equilibrium of Heterogeneous Substances
  On the Equilibrium of Heterogeneous Substances is a foundational 1876–1878 treatise in thermodynamics by Josiah Willard Gibbs that introduced key concepts of chemical thermodynamics and phase equilibrium, including the Gibbs free energy.
• B. Gibbs free energy
  Gibbs free energy is a thermodynamic potential that predicts the spontaneity of processes and the maximum non-expansion work obtainable from a system at constant temperature and pressure.
• C. Arrhenius equation for temperature dependence of reaction rates
  The Arrhenius equation for temperature dependence of reaction rates is a fundamental formula in chemical kinetics that quantitatively relates a reaction’s rate constant to temperature and activation energy, explaining why reactions speed up as temperature increases.
• D. Flory–Huggins solution theory
  Flory–Huggins solution theory is a thermodynamic model that describes the mixing behavior and phase separation of polymer solutions by accounting for the size difference between polymer chains and solvent molecules.
• E. Carathéodory’s formulation of the second law of thermodynamics
  Carathéodory’s formulation of the second law of thermodynamics is a mathematically rigorous restatement of the second law based on the inaccessibility of certain thermodynamic states, providing a foundation for the concept of entropy without relying on cyclic processes or heat engines.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
