The units of constant 'a' in van der Waals equation is `:`

A

`dm^(6)` atm `mol^(-2)`

B

`dm^(3)` atm `mol^(-1)`

C

dm atm. `mol^(-1)`

D

atm `mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
Units of .a. = `L^(2)` atm, `mol^(-2)`
`1L = 1 dm^(3)`
Hence units of .a. = `dm^(6)` atm `mol^(-2)`
