    Equation for a real gas is \[\left( P+\frac{a}{{{V}^{2}}} \right)(V-b)=RT\] Where\[P=\]pressure, \[V=\]volume, a, b and R constants, dimensional formula of a is:

    A) \[{{L}^{6}}\]

    B) \[{{M}^{1}}{{L}^{-1}}{{T}^{-2}}\]

    C)  \[{{M}^{1}}{{L}^{5}}{{T}^{-2}}\]

    D) \[{{L}^{3}}\]

    Correct Answer: C

    Solution :

     \[\left( P+\frac{a}{{{V}^{2}}} \right)(V-b)=RT\] Dimensional formula of \[a=\]Dimensions of \[P\times \]dimensions of \[{{V}^{2}}\] \[=[M{{L}^{-1}}{{T}^{-2}}][{{L}^{6}}]\] \[=[M{{L}^{5}}{{T}^{-2}}]\]
