The ratio a/b (the terms u8sed in van der Waals' equation) has the unit .

A

atm litre `mo1^(-1)`

B

atm `dm^(3) mo1^(-1)`

C

dyne `cm mo1^(-1)`

D

All of these

Text Solution

Verified by Experts

Unit of ` a = "atm litre"^(2) mo1^(-2)`
` ="atm dm"^(6) mo1^(-2)`
`= "dyne" cm^(4) mo1^(-2)`
Unit of ` b= "litre mo1"^(-1)`
` =dm^(3) mo1^(-1) =cm^(3) mo1^(-1)` .
