Question

If the various terms in the given below expressions have usual meanings, the van't Hoff factor (i) cannot be calculated by which one of the following expressions (A) π V=√i n R T (B) Δ Tf=i Kf ⋅ m (C) Δ Tb=i Kb ⋅ m (D) (P text solvent °-P text solution /P text solvent °)=i((n/N+n))

Tardigrade Admin · Accepted Answer

Van't Hoff equation is π V=i n R T For depression in freezing point. Δ Tf=i × Kf × m For elevation in boiling point. Δ Tb=i × Kb × m For lowering of vapour pressure, (P text solvent °-P text solution /P text solvent °)=i((n/N+n))

Q. If the various terms in the given below expressions have usual meanings, the van't Hoff factor $(i)$ cannot be calculated by which one of the following expressions

$πV = in RT$

$Δ T_{f} = i K_{f} \cdot m$

$Δ T_{b} = i K_{b} \cdot m$

$\frac{P _{solvent}^{\circ} - P _{solution}}{P _{solvent}^{\circ}} = i (\frac{n}{N + n})$

Van't Hoff equation is $πV = in RT$
For depression in freezing point.
$Δ T_{f} = i \times K_{f} \times m$
For elevation in boiling point.
$Δ T_{b} = i \times K_{b} \times m$
For lowering of vapour pressure,
$\frac{P _{solvent}^{\circ} - P _{solution}}{P _{solvent}^{\circ}} = i (\frac{n}{N + n})$
