(c) 1
Explanation:
Compressibility factor (Z) is a convenient method of showing deviation of real gases from an ideal gas
Z = PV/nRT
For ideal gas, PV = nRT ; ∴ Z = 1
For real gases, PV ≠ nRT ; ∴ Z ≠ 1
When, Z !1, it refers positive deviation i.e., gas is less compressible than ideal gas. Z < 1, it refers negative deviation, i.e., gas is more compressible than ideal gas.
