Vander Waal's equation of state is obeyed by real gases. For n moles of a real gas, the expression will be                                 [IIT 1992; Pb. CET 1986; DPMT 1986]

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)                 \[\left( P+\frac{{{n}^{2}}a}{{{V}^{2}}} \right)\,(V-nb)=nRT\]
