It is observed that H_(2) and He gases always show positive deviation – InterviewSolution

1.	It is observed that H_(2) and He gases always show positive deviation from ideal behaviour i.e ., Zgtl. This is because
Answer» the value of 'a' is very large due to HIGH ATTRACTIVE FORCES the weak intermolecular forces of ATTRACTION due to which 'a' is very small and `(a)/(V^(2))` is negligible the value of 'b' is very large due to large size of the moecules both 'a' and 'b' are very small and negligible Answer :B
