Question
If Z is a compressibility factor, van der Waals equation at low pressure can be written as
Options
A.
B.
C.
D.
Solution
Compressibility factor (Z) = 
(For one mole of real gas)
van der Waal equation
(V - b) = RT
At low pressure
V - b ≈ V
V = RT
PV +
= RT
PV = RT -
So,
(For one mole of real gas)
van der Waal equation
(V - b) = RTAt low pressure
V - b ≈ V
V = RTPV +
= RTPV = RT -
