Calculate the pressure in bar of 1350 mol krypton in a 175.0 L container at 298 K, if a = 2.325 L2barmol−2 and b = 0.0396 Lmol−1.
Ans :-
From Real gas equation :
.........................(1)
Here,
P = Pressure of Krypton = ?
a = Molecular interaction constant = 2.325 L2 bar mol-2 (given)
b = Volume correction constant = 0.0396 L mol-1
n = Number of moles of Krypton = 1350 mol (given)
V = Volume = 175.0 L (given)
T = Temperature = 298 K (given) and
R = Universal gas constant = 8.314 x 10-2 L.bar .K-1.mol-1
Now, From equation (1), we have
P = 4.19 x 106 bar
