Van't Hoff factors of aqueous solutions of `X`,`Y` and `Z` are `2.8`,`1.8` and `3.5` respectively. Which of the following statement(s) is (are) correct?
a.`BP:XltYltZ`
b.`FP:ZltXltY`
c.Osmotic pressure,X=Y=Z
d.`VP:YltXltZ`

Explanation

Observed colligative property=`ixx`Normal colligative property
a. Elevation in `BP` follows the order:`YltXltZ`
`rArr BP` following the order : `YltXltZ`
b. Depressin in `FP` follows the order,
`YltXltZT_(f)=T_((f)^(@)-DeltaT_(f))`
`rArr FP` following the order :`ZltXltY`
c. Osmotic pressure follows the order: `YltXltZ`
d.Relative lowering in the `VP` follows:
`YltXltZ`
`VP` follows the order: `ZltXltY`
