For one mole of a van der Waals' gas when `b=0` and `T=300K`, the `pV vs 1//V` plot is shown below. The value of the vander Waals' constant `a`(atm `L mol^(-2)`)

A

`1.0`

B

`4.5`

C

`1.5`

D

`3.0`

Text Solution

Verified by Experts

The correct Answer is:
C
`(P+(a)/(V^(2)) (V) = RT`
`PV +a//V RT`
`PV = RT -a(v)`
`y = RT - a(x)`
So, slope `=a =(21.6 -20.1)/(3-2) = (1.5)/(1) = 1.5`
