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

Options

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

Answer

D

Explanation

`{:(,a,b),(CI_(2),6.579 L^(2) "bar mol"^(-2),0.05622 L "mol"^(-1)),(C_(2)H_(5),5.562 L^(2)"bar mol"^(-2),0.06380 L "mol"^(-1)):}`
