1.	One mole of a monoatomic real gas satisfies the equation `p(V-b)=RT` where `b` is a constant. The relationship of interatomic potential `V(r)` and interatomic distance `r` for gas is given byA. B. C. D.
Answer» Correct Answer - C Equation of stage `p(v-b) = RT` indicates that inter molecular forces of attraction or repulsion are absent. As a result. Interatomic potential `V_(r)` remains constant on increasing pressure in the beginning. As the molecular come very close on increasing pressure. their electronic and nuclear repulsion leading to interatomic potential increases abrupty.

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressyre and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas beheviour as compared to the gases which are liqufied with diffculty. Gas deviates from ideal gas beheviour because moleculesA. are coloulessB. attract each otherC. contain covalent bondD. show Brownian Movement.
