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

Options

A. a and b for `CI_(2) gt a` and b for `C_(2)H_(6)`
B. a and b for `CI_(2) gt a` and b for `C_(2)H_(6)`
C. a for `CI_(2) gt` a for `C_(2)H_(6)` but b for `CI_(2) lt b` for `C_(2)H_(6)`
D. a for `CI_(2) lt` a for `C_(2)H_(6)` but b for `CI_(2) gt` b for `C_(2)H_(6)`

Answer

C

Explanation

`{:(,a(dm^(3)atmmol^(-2)),b(dm^(3)mol^(-1)),,),(CI_(2),6.49,0.0562,,),(C_(2)H_(6),5.49,0.0638,,):}`
From the above values a for `CI_(2)gt` a for ethane b for ethane gt b for `CI_(2)` .
