Question #14cfe

Answer 1

AS `a/v^2` is added with P, the pressure .This term `a/v^2` will have unit of pressure.
Again `v` is the molar volume . so unit of `v` may be `Lmol^-1`

If the unit of pressure `P` is taken as `atm`, then unit of a will be

`"Unit of a"="Unit of "Pxx "Unit of " v^2=atmL^2mol^-2`

If the unit of pressure `P` is taken as `Pa=Nm^-2` and unit of molar volume as `m^3mol^-1`, then unit of a will be

`"Unit of a"="Unit of "Pxx "Unit of " v^2`

`=Nxxm^-2m^6mol^-2`

`=Nxxm^4mol^-2`
