Van der Waal equation for CH(4) at low p...

Van der Waal equation for `CH_(4)` at low pressure is

A

`PV = RT – Pb`

B

`PV = RT- (a)/(V)`

C

`PV= RT+(a)/(V)`

D

`PV = RT + Pb`

Text Solution

Verified by Experts

The correct Answer is:
B
`(P+(a)/(V_(m)^(2)))(V_(m)-b)=RT`
At low P, volume V is high `(V – b)V`
`(P+(a)/(V^(2)))(V)=RT`
`PV = RT- (a)/(V)`
