van't Hoff equation
Pronunciation: vahnt hof
Definition:
- equation for osmotic pressure of dilute solutions.
- for any reaction, d(ln Keq)/d(1/T) equals −ΔH/R where Keq is the equilibrium constant, T the absolute temperature, R the universal gas constant, and ΔH the change in enthalpy; thus, plotting ln Keq vs. 1/T allows the determination of ΔHo and ΔSo, where ΔHo and ΔSo are the standard changes in enthalpy and entropy, respectively.
