The behaviour of a real gas. is usually depicted by plotting.compression factor Z(= `pV_(m)//RT`) versus p at a constant temperature. These plots are explained on the basis of van der Waals equation `(p+a//V_(m)^(2))(V_(m) -b)=RT`
The value of Z lt 1`.is observed provided

A

p is low and `T gt T_(B)` (Boyle temperature)

B

p is low and T `lt T_(B)`

C

p is low and T = `T_(B)`

D

p is high and `T lt T_(B)`

Text Solution

Verified by Experts

The correct Answer is:
B
The value is `Z lt 1` provided `T lt T_(B)` and pressure is low

At low pressure, the vander Waal's equation is written as (P + (a )/(V ^(2))) V = RT. The compressibility factor is then equal to

Indicate whether the following statement is true or false. Justify your answer. In the van der Waal's equation. [p+(n^2 a)/V^2] (V-n b)=nRT the constant a reflects the actual volume of the gas molecules.
