Onsager’s Reciprocity Relations:
Onsager’s reciprocity relations are a set of equations that describe the relationship between the fluxes and forces in a system that is not in equilibrium. These relations are of fundamental importance in nonequilibrium thermodynamics and have applications in a wide variety of fields, including physics, chemistry, and biology.
Key Points:
-
Onsager’s reciprocity relations state that the coefficients relating fluxes and forces in a system are symmetric, i.e., the coefficient relating the flux of one quantity to the force of another quantity is equal to the coefficient relating the flux of the second quantity to the force of the first quantity.
-
These relations are a consequence of the principle of microscopic reversibility, which states that the microscopic processes that occur in a system are time-reversible.
-
Onsager’s reciprocity relations have important implications for the behavior of systems in nonequilibrium. For example, they can be used to predict the direction of heat flow in a system and to … Read full answer
