The van der Waal's equation of state for...

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 dimensions of ` a` are

A

`[ML^(5)T^(-2)]`

B

`[ML^(-1)T^(-2)]`

C

`[L^(3)]`

D

`[L^(6)]`

Text Solution

Verified by Experts

`(a)/(v^(2))` is dimensionally equal to P
`(a)/((L^(3))^(2))=M^(1)L^(-1)T^(-2)rArra=M^(1)L^(5)T^(-2)`
