If `Z` is a compressibility factor, van der Waals' equation at low pressure can be written as

A

`Z = 1+(RT)/(Pb)`

B

`Z = 1-(a)/(VRT)`

C

`Z = 1-(Pb)/(RT)`

D

`Z = 1 +(Pb)/(RT)`

Text Solution

Verified by Experts

The correct Answer is:
B
In low pressure region, vanderwaal equation becomes
`Z = 1 - (a)/(RTV_(m))`
