A) \[\left( \frac{p}{n}+\frac{na}{{{V}^{2}}} \right)\left( \frac{V}{n-b} \right)=RT\]
B) \[\left( P+\frac{a}{{{V}^{2}}} \right)(V-b)=nRT\]
C) \[\left( P+\frac{na}{{{V}^{2}}} \right)(nV-b)=nRT\]
D) \[\left( P+\frac{{{n}^{2}}a}{{{V}^{2}}} \right)(V-nb)=nRT\]
Correct Answer: D
Solution :
van der Waals equation for the n moles of a real gas is \[\left( p+\frac{{{n}^{2}}a}{{{V}^{2}}} \right)(V-nb)=nRT\]
