Question

Compressibility factor for H2 behaving as a real gas is??

Answer 1

Factor is molecular apace, Ti has maximise inter molecular space

Answer 2

Compressibility factor the ratio of PV and nRT.

It can be written as:

$Z=\frac{P V}{n R T}$

For 1 mole of gas which behaves ideally; the value of compressibility factor will be 1. Whereas for real gases, it can be check with the help of Vander wall gas equation:

$P V=P b+R T$

Divide both sides with RT;

$\frac{P V}{R T}=1+\left(\frac{P b}{R T}\right)$

Hence the compressibility factor $Z=\frac{P V}{R T}$  

$\bold{Z=1+\left(\frac{P b}{R T}\right)}$.
