If the various terms in the following expressions have usual meanings, the van't Hoff factor 'i' cannot be calculated by which of the following expression ?

Answer»

<P>`PI V = inRT`
`DeltaT_(F) = iK_(f)m`
`DeltaT_(b) = iK_(b)m`
`(p_("solvent")^(@)-p_("solution"))/(p_("solvent")^(@)) = i((N)/(N+n))`

Solution :For relative lowering of V.P., expression is
`(p^(@)-p_(s))/(p^(@)=(i n)/(N+ i n)`
For very dilute solution,
`(p^(@)-p_(s))/(p^(@)=(i n)/((N)`
