Question 1
1 / -0

‘a’ and ‘b’ are van der Waals’ constants for gases. Chlorine is more easily liquefied than ethane because

A
A and b for Cl₂ > a and b for C₂H₆

B
A and b for Cl₂ < a and b for C₂H₆

C
A for Cl₂ < a for C₂H₆ but b for Cl₂ > b for C₂H₆

D
A for Cl₂ > a for C₂H₆ but b for Cl₂ < b for C₂H₆

Solution

Compressible gases have greater force of attraction and hence value of ‘a’ should be greater and reduced volume ‘b’ should be less.
Hence, option D is correct.
