Osmotic potential equation

WebThe second virial coefficient represents the initial departure from ideal-gas behavior. The second virial coefficient, in three dimensions, is given by: B2(T) = − 1 2∫ (exp( − Φ12(r) kBT) − 1)4πr2dr. where Φ12(r) is the intermolecular pair potential, T is the temperature, and kB is the Boltzmann constant. http://lawr.ucdavis.edu/classes/ssc107/SSC107Syllabus/chapter2-00.pdf
