Question
The compressibility factor of an ideal gas is :
Options
A.0
B.2
C.1
D.4
Solution
Compressibility factor (Z) is a convenient method of showing deviation of real gasesfrom an ideal gas
Z =
For ideal gas, PV = nRT ; ∴ Z = 1
For ideal gases PV ≠ nRT; ∴ Z ≠ 1
When, Z > 1, refers positive deviation i.e., gas is less compress ible than ideal gas. Z < 1, it refers positive devition i.e., gas is more compressible than ideal gas.
