dU/dV in van der Waals equation of state derivation
Previous, I proved that
$$\frac{T_2}{T_1}^{C_V/(C_p-C_V)}=\frac{V_1}{V_2}$$
I've been asked to derive a similar expression for a gas that obeys the equation of state
$$p=\frac{RT}{(\overline{V}-b)}$...

How to determine if pressure surpasses capacity with the van der Waals equation of state?
I have to decide whether a $\pu{20 L}$ container with $\pu{0.8 kg}$ ethane can withstand the pressure at $\pu{373.15 K}$. The following information is given:
\begin{align}
b &= \pu{6.448x10^-2 ...
