LARS ONSAGER Meaning and
Definition
-
Lars Onsager (1903-1976) was a Norwegian-American physical chemist who made significant contributions to the field of thermodynamics. He is particularly renowned for his work on irreversible thermodynamics and the understanding of non-equilibrium phenomena.
Onsager's most influential contribution was his development of the Onsager reciprocal relations, also known as the Onsager symmetry relations. These relations, derived from statistical mechanics, describe the relationships between the thermodynamic driving forces and the corresponding fluxes in systems that are far from equilibrium. They represent a fundamental link between microscopic reversibility and macroscopic irreversibility in physical processes, allowing the prediction of the behavior of systems out of equilibrium.
Additionally, Onsager formulated the concept of the reciprocal relation between electrical conductivity and diffusion coefficients for charged particles in electrolytes. This work, now known as the Onsager's law of electrolytic conductivity, has been instrumental in understanding and explaining the transport of ions in solutions.
Overall, Lars Onsager's major contributions to the field of physical chemistry have had a lasting impact on the understanding of thermodynamics, especially in systems far from equilibrium. His work has provided fundamental principles and relationships that continue to be fundamental in the study of various scientific and engineering disciplines, offering valuable insights into the behavior of complex systems.
