Given that `DeltaT_(f)` is the depression in freezing point of the solvent in a solution of a non-volatile solute of molarity `m`,the quantity `underset(m rarr0)(Lt) (DeltaT_(f)//m)` is equal to ……………. .

A

Zero

B

One

C

Three

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
D
`DeltaT_(f)=mxxK_(f)`
`(DeltaT_(f))/(m)=K_(f)`
`underset(mrarr0)(lim)((DeltaT_(f))/(m))` will remain a constant value as `K_(f)` is constant for a solvent.
