Chemistry - Real Gas Question with Solution | TestHub

(I) $Z\to 1$ as $P\to 0$ for a real gas

At very low pressure, a real gas behaves ideally.

(II) $Z<1$ as $P\to 0$

At slightly higher $P$, attractive forces dominate $\to Z<1$.

(III) $Z\to 0$ at a pressure where repulsive & attractive forces are comparable

$Z=1$ when gas behaves ideally; it does not go to zero.

(IV) At point X, intermolecular attractive forces dominate over repulsive forces

(V) At point Y, potential energy is maximum

Attractive forces give minimum potential energy $\to V_{min}$.

Correct statements: I, II, IV
