(B) The compressibility factor is defined as $Z = \frac{PV_m}{RT}$.For an ideal gas,$Z = 1$ and $V_m = 22.4 \ L$ at $NTP$.If $Z > 1$,the gas shows positive deviation from ideal behavior,meaning the repulsive forces are dominant.Consequently,the molar volume $V_m$ is greater than the ideal molar volume,i.e.,$V_m > 22.4 \ L$ at $NTP$.
