At low pressure the van der Waals' equation is reduced to `[P +(a)/(V^(2)]]V =RT` The compressibility factor can be given as .

A

`1 - (a)/(RTV)`

B

`1 - (a)/(RTV)`

C

`1 + (a)/(RTV)`

D

`1 + (a)/(RTV)`

Text Solution

Verified by Experts

`(P+(a)/(V^(2)))V=RT`
or `PV+(a)/(V) =RT`
or `(PV)/(RT) + (a)/(RTV) =1`
or `(RV)/(RT) =(1-(a)/(RTV)) =Z` .
