Positive deviation from ideal behaviour takes place because of

Options

A. molecular interaction between atoms and `PV //nRT gt 1`
B. molecular interaction between atoms and `PV//nRT lt 1`
C. finite size of atoms and `PV//nRT gt 1`
D. finite size of atoms and `PV//nRT lt 1`

Answer

A

Explanation

Positive deviation corresponds to `Z gt 1 :'Z = (pV)/(nRT)`, for positive deviation, `(pV)/(nRT) gt 1`
