Write the van der Waals equation.
(N/A) The van der Waals equation for $n$ moles of a real gas is given by: $\left(p + \frac{an^2}{V^2}\right)(V - nb) = nRT$,where $p$ is the pressure,$V$ is the volume,$T$ is the temperature,$R$ is the universal gas constant,and $a$ and $b$ are the van der Waals constants.
