Question

Critical temperature and pressure of a real gas is ${27}^{o}C$ & 150 atm respectively. The critical volume of 1 mole of real gas is :

• A. o.12
• B. 0.24
• C. 0.5
• D. None

Answer 1

Answer: (B)

0.24

$Z_C=\frac{P_C.V_C}{R{T}_C}$

and $P_c{V}_c=\frac{3}{8}R{T}_c$

Given, $P_C=150atm,T_C=27+273=300$

$V_C=?,mole=1$

$\frac{3}{8}=\frac{150\times V_C}{0.0821\times 300}$

$V_C=\frac{3}{8}\times \frac{24.63}{150}$

$=0.24$

Hence, the correct option is $\text{B}$
