Question

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

• A. a for $Cl _{2}>$ a for $C _{2} H _{6}$ but $b$ for $Cl _{2}< b$ for $C _{2} H _{6}$
• B. a and b for $Cl _{2}> a$ and $b$ for $C _{2} H _{6}$
• C. $a$ and $b$ for $C l_{2}
• D. a for $Cl _{2}< a$ for $C _{2} H _{6}$ but $b$ for $Cl _{2}> b$ for $C _{2} H _{6}$

Answer 1

Answer: (B)

Both a and $b$ for $Cl$ is more than $C _{2} H _{6}$
