(A)Molecular interaction between atoms and Correct
(B)Molecular interaction between atoms and
(C)Finite size of atoms and
(D)Finite size of atoms and

Answer: (A)

Solution

A positive deviation means , i.e. the gas is less compressible than ideal behaviour predicts — this happens when repulsive (volume-excluding) molecular interactions dominate over
