(r) = ∞ for r < 6 and
(r) = 0 for r > σ.
The second virial coefficient, \( B_2 \), quantifies the deviation of a real gas from ideal gas behavior due to intermolecular interactions. It is given by the integral: \[ B_2 = -\frac{1}{2} \int d\mathbf{r} \, f(r) \] where \( f(r) \) is the Mayer f-function: \[ f(r) = e^{-\beta \phi(r)} - 1 \] where \( \beta = \frac{1}{k_B T} \) and \( \phi(r) \) is the intermolecular _________ _______ ____ ______ _____ _______ _______ _____ _____ _______ _____.
