Explore advanced thermodynamics concepts in this MIT lecture focusing on nonequilibrium theory and its applications. Delve into the relationships between rates and affinities in both far and near equilibrium conditions, examining detailed kinetic mechanisms through hydrocarbon oxidation examples. Master the linearization of rate-affinity relations and understand Onsager reciprocity through the principle of maximum entropy production. Learn about thermal conductivity tensors in anisotropic materials, the Fourier law of thermal conduction, and the Cattaneo-Vernotte heat equation. Taught by Professor Gian Paolo Beretta, the lecture provides comprehensive coverage of topics ranging from Ziegler orthogonality relations to steady-state heat flux analysis. Access accompanying course materials, including detailed slides and a complete analytical index, to enhance understanding of these advanced thermodynamic principles. For optimal learning efficiency, viewing at 1.5x speed is recommended.
