One mole of a monoatomic real gas satisfies the equation where b is a constant. The relationship of interatomic potential and interatomic distance r for the gas is given by







Options
- A

- B

- C

- D

Correct answer
C. 
Step-by-step solution
Here the given equation is .
On comparing with van der Waals' equation
\left[P + \dfrac{a}{V^{2}}\right] [ V - b ] = RTa = 0.
It means only repulsive forces are present which are contributive only at very close distance so the potential energy will increase abruptly. i.e., graph C is correct.
