It is observed that `H_(2)` and He gases always show positive deviation from ideal behaviour i.e ., `Zgtl`. This is because

A

the value of a is very large due to high attractive forces

B

the weak intermolecular forces of attraction due to which a is very small and `a/V^(2)` is negligible

C

the value of b is very large due to large size of the molecules

D

both a and b are very small and negligible .
