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 the gas is given by:

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
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.
