Incorrect relationship for mole fraction...

Incorrect relationship for mole fractionis :-

A

`xlt1`

B

`0ltxlt1`

C

`-2ltxlt+2`

D

Always positive

Text Solution

Verified by Experts

The correct Answer is:
C
`i=(DeltaT_(f))_(obs)/(DeltaT_(f))_(Theo)=((DeltaT_(f))obs)/(K_(f)xxmolality)`
`i=(0.558)/(1.86xx0.1)=3`
for `Hg(NOO_(3))_(2)hArrHg^(+2)+2NO_(3)^(-)`
`i=1-alpha+nalpha`
`because3=1+alpha(n-1)`
`alpha=(3-1)/(3-1)=1` or 100%
