The equation of state for one mole of a gas is: P = RT/(V − b) − a/(T·V²), where V is the molar volume and a and b are constants different from van der Waals constants.

The minimum pressure needed for liquefaction of the gas at the temperature calculated above is

Options:

Answer:
D
Solution:

Pc = RTc/2b - a/(9b²Tc) with Tc = √(8a/27Rb), Vc = 3b. The two terms are (√(6))/9√(aR/b³) and (√(6))/12√(aR/b³), so Pc = (√(6))/36√(aR/b³) = √(aR/216b³). Hence Ans (d).
