“…It provides the bedrock for understanding numerous natural phenomena and for design and optimization of chemical processes. The importance of statistical mechanics in chemical engineering has been recognized for many years 3‐5. One prominent example, primarily from the 1960s and 1970s, is the development and application of equations of state and local‐composition models, attained by ingenious combinations of basic concepts from statistical mechanics (in particular, van der Waals equation of state and Boltzmann's distribution law) with extensive experimental data 6, 7.…”
