Which is/are correct statement about Vanderwaals real gas:

Answer:

A, B, C

Solution:

For a van der Waals real gas:

(A) $T_{B} = \frac{a}{b R} T_{C} = \frac{8}{27} \frac{a}{b R}$ Correct

(B) $Z = 1 + (b - \frac{a}{RT}) \frac{1}{V} + \frac{b ^{2}}{V ^{2}} + \dots$ . at boyles temperature

V.S.C. =0 $b - \frac{a}{R T} = 0$ $T = \frac{a}{b R}$ = $T_{B}$ (Correct)

At critical point $Z_{C} = \frac{3}{8} = 0.375$

Attractive forces dominate over repulsive forces. (Correct)

D) Incorrect
