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`

Options

A. `b.p:XltYltZ`
B. `f.p.ZltXltY`
C. osmotic pressure: `X=Y=Z`
D. `v.p.:YltXltZ`

Answer

B

Explanation

As van't Hoff factor increases `RLVP` increases i.e., `V.P.` devreases `ygtxgtz`
Elevation in `b.p.` increases i.e., b.p. increases `yltxltz`
Depresion in f.p. increases i.e., f.p decreases `ygtxgtz`
Osmotic pressure increases so `yltxltz.
