The van der Waal's equation of state for some gases can be expressed as :
`(P + (a)/( V^(2))) ( 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 dimensionsal representation of `ab// RT` is

Options

A. `ML^(5)T^(-2)`
B. `M^(0) L^(3) T^(0)`
C. `ML^(-1)T^(-2)`
D. None of these

Answer

D

Explanation

`[(ab)/(V^(2))] = [RT] rArr [(ab)/(RT)] = [V^(2)] = [L^(6)]`
