(c) (10 pts) The second virial coefficient for a gas interacting with a potential $U(r)$ is given by: $B_2(T) = -2\pi \int_0^\infty r^2 \left( e^{-\beta U(r)} - 1 \right) dr$. Show that for the square well potential, $B_2$ is given by: $B_2(T) = \frac{2}{3} \pi \sigma^3 \left[ 1 - (\alpha^3 - 1)(e^{\beta \epsilon} - 1) \right]$. (d) (5 pts) What is the $T \to \infty$ limit of this $B_2(T)$? Explain the significance of this. (e) (5 pts) The \"Boyle temperature\" $T_B$ is the temperature for which $B_2(T) = 0$. Show that:
