### What are the dimensions of a and b/in Vander Wall's equation P A v 2 )( VB )= RT?

The Van der Waals equation of state for some gases can be expressed as: (P+aV2)(V−b)=RT, where P is the pressure, V is the molar volume, and T is the absolute temperature of the given sample of gas and a, b and R are constants. The dimensions of a are: (A) ML5T−2. (B) ML−1T−2.
