When non-ideal solution was prepared by mixing 30 mL chloroform and 50 mL acetone. The volume of mixture will be

Options

A. `gt 80` mL
B. `lt 80` mL
C. `= 80` mL
D. `ge 80` mL

Answer

B

Explanation

Chloroform & acetone form a non-ideal solution, in which A.....B type interaction are more than A......A & B......B type interaction due to H -bonding. Hence, the solution shows, negative deviation from Raoult’s Law i.e.,
`DeltaV_(mix)=-ve, DeltaH_(mix)=-ve`
`therefore` Total volume of solution = less than (30 + 50)mL or `lt80 mL`.
