Question

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

Answer 1

Correct option is (C)

At large inter-ionic distances (because a → 0) the P.E. would remain constant. However, when r → 0; repulsion would suddenly increase.
