Chemistry - Real Gas Question with Solution | TestHub

At low pressure and high temperature, real gases behave like ideal gases. Accordingly, Van der Waals equation is modified as:

${\text{pV}}_{\text{m}}=\text{RT}$(for 1 mole)

$\because$At low pressure and high temperature, the terms$\frac{\text{a}}{{\text{V}}^{\text{2}}}$and$\text{b}$becomes very small as compared to$\text{p}$and$\text{V}$.
