# Under critical conditions , the compressibility factor for a gas is

$(a)\;\large\frac{3}{8}\qquad(b)\;\large\frac{8}{3}\qquad(c)\;1\qquad(d)\;\large\frac{1}{4}$

Since $\large\frac{RT_C}{P_CV_C} = \large\frac{8}{3}$
$\therefore Z = \large\frac{P_CV_C}{RT_C} = \large\frac{3}{8}$ (at critical conditions)
