Question

The value of compressibility factor for one mole of a gas under critical states is:

• A. 3/8
• B. 2/3
• C. 8/27
• D. 27/8

Answer 1

The correct option is A 3/8

Solution:

since $\frac{R{T}_C}{P_C{V}_C}$ =$\frac{8}{3}$

$\therefore Z=\frac{P_C{V}_C}{R{T}_C}=\frac{3}{8}$(at critical conditions)

Hence,$\frac{3}{8}$ is the answer.
