Kirkwood's theory

Kirkwood's theory, often called the Kirkwood-Buff theory, connects microscopic details of molecules in a solution to their macroscopic properties, such as temperature or pressure. It uses statistical mechanics to analyze how molecules are distributed relative to each other, considering their interactions and arrangements. This helps predict how solutions behave in different conditions by linking the arrangement of molecules at the microscopic level to observable properties. Essentially, it provides a framework to understand the structure and thermodynamics of complex mixtures based on how molecules are dispersed and interact within them.
