Which one of them is more volatile component?

Options

A. `CH_(2)Cl_(2)`
B. `CHCl_(3)`
C. Both a and b
D. Not able to determine

Answer

a

Explanation

Since, `CH_(2)Cl_(2)` is a more volatile component than `CHCl_(3).[p_(CH_(2)Cl_(2))^(@) = 415 mm Hg` and `p_(CHCl_(3))^(@) = 200 mm Hg]` and the vapour phase is also richer in `[y_(CH_(2)Cl_(2)) = 0.82]` and `[y_(CHCl_(3)) = 0.18]`
