Fugacity & coefficient

Layer 2 — Chemistryin the chemical-thermodynamics subtree

Lewis 1908 fugacity f corrects ideal-gas chemical-potential μ = μ° + RT ln(f/p°) for non-ideality; fugacity-coefficient φ = f/p captures intermolecular interactions. Equation-of-state (vdW, Redlich-Kwong, Peng-Robinson) integration yields…
