Q. Positive deviation from ideal behaviour takes place because of

A) Molecular interaction between atoms and $pV/nRT > 1$
B) Molecular interaction between atoms and $pV/nRT < 1$
C) Finite size of atoms and $pV/nRT > 1$
D) Finite size of atoms and $pV/nRT < 1$
Explanation

(a)
If $Z > 1$, the gas is less compressible than expected from ideal behaviour and shows positive deviation usually at high pressure, $ie,\ pV > RT$
