The van der Waals equation is `[P+(n^(2)a)/(V)] (V -nb) =nRT` for n moles where a and b are van der Waals' constants Which of the following statements are true about a and b when the temperature of the gas is too low ?.

A

Both remains same

B

a remains same b varies

C

a varies, b remains same

D

both varies

Text Solution

Verified by Experts

The van der Waals constants a and b proposed to be characteristic contant were found to vary with temperature and pressure. This is one of the limitation of van der Waals' equation .
