One mole of a monoatomic real gas satisfies the equation P(v-b)=R T where, b is a constant. The relationship of interatomic potential V(r) and interatomic distance r for gas is given by -
Equation of state p(v-b)=R T, indicates absence of intermolecular attraction or repulsion, hence inters atomic potential remains constant on increasing ' ' in the beginning. As the molecules come very close, their atomic electronic and nuclear repulsion increases abruptly.
