(C) I, III only
Step-by-step Solution
Detailed explanation
(I) Compressibility factor (z), is the ratio of PV and nRT. Mathematically, \(Z=\frac{P V}{n R T}\) \(\mathrm{Z}=1\) at all temperatures and pressures, for an ideal gas, because for a ideal gas. \(\mathrm{pV}=\mathrm{nRT}\) (II) For one mole of an ideal gas…
