Question
′a′ and ′b′ are van der Waals′ constants for gases. Chlorine is more easily liquefied than ethane because
Options
A.a and b for Cl2 < a and b for C2 H6
B.a for Cl2 < a for C2 H6 but b for 2 Cl > b for C2 H6
C.a for Cl2 > a for C2 H6 but b for 2 Cl < b for C2 H6
D.a and b for Cl2 > a and b for C2 H6
Solution
ease of liquefaction ∝ 
for ethane a = 5.49, b = 0.0638
for Cl2 a = 6.49, b = 0.0562
for ethane a = 5.49, b = 0.0638
for Cl2 a = 6.49, b = 0.0562
