Dear Aspirant,

Vant Hoff factor =i
For Barium nitrate,i=3,
2Ba+ No3-

For Nacl,i=2Na+ Cl-
i=2 vant Hoff factor

For glucose vant Hoff factor will be 1
I=1

So higher the vant Hoff factor higher will be the loweirng of vapour pressure.
So barium nitrate will have highest lowering in vapour pressure

Order will be barium nitrate>Nacl>glucose

Thanks
All the very best.
