Write the Van der Waals equation for a real gas. Explain the correction term for pressure and volume.

Explanation

Vander Waals equation of stab for real gases is `(P+(an^(2))/(V^(2)))(V-nb)=nRT`
Correction term for pressure :
`(an^(2))/(V^(2))` is the pressure correction. It represents the intermolecular interaction that causes the non-ideal behavior.
Correction term for volume :
V-nb is the volume correction. It is the effective volume occupied by real gas.
