The critical temperature and pressure of a real gas are -73°C and 41 atm respectively. The critical volume of 1 mole of the gas is $(R = 0.082 L atm K^{- 1} mol^{- 1})$

Options:

Answer:

Solution:

$T_{c} = - 73 + 273 = 200 K$ .

For a van der Waals gas $Z_{c} = P_{c} V_{c} / (R T_{c}) = 3/8$ .

$V_{c} = (3/8) \times 0.082 \times 200/41 = (3/8) \times 0.40 = 0.15 L$ .

( 0.40 L is $R T_{c} / P_{c}$ and 0.05 L is b.)

Answer: (C).
