Vedclass · Answer

(D) The Van der Waals equation is a modified form of the ideal gas equation that accounts for the non-ideal behavior of real gases.For $n$ moles of a real gas,the equation is given by:$\left(P+\frac{an^2}{V^2}\right)(V-nb)=nRT$Expanding this expression:$P(V-nb) + \left(\frac{an^2}{V^2}\right)(V-nb) = nRT$$PV - Pnb + \frac{an^2}{V} - \frac{an^2b}{V^2} = nRT$Rearranging the terms,we get:$PV + \frac{an^2}{V} - \frac{an^2b}{V^2} - Pnb = nRT$Thus,option $D$ represents the expanded form of the Van der Waals equation.

Which of the following represents the Van der Waals equation for $n$ moles of a gas?
