Darken's equations are a set of thermodynamic relations in physical chemistry, specifically related to the diffusion of species in multicomponent systems. They provide a way to relate the fluxes of components in a mixture to their concentrations, and are particularly useful in describing transport phenomena in liquid mixtures and solid solutions. The key components of Darken's equations include: 1. **Diffusion Flux**: The flux of a component \( i \) is represented by \( J_i \).
