Question

A gas at $350	ext{ K}$ and $15	ext{ bar}$ has molar volume $20$ percent smaller than that for an ideal gas under the same conditions. The correct option about the gas and its compressibility factor $(Z)$ is :

Accepted Answer

Compressibility factor $(Z) = \frac{V_{real}}{V_{ideal}}$. $\because V_{real} < V_{ideal}$; Hence $Z < 1$. If $Z < 1$, attractive forces are dominant among gaseous molecules and liquefaction of gas will be easy.
