An Intiative by Sri Chaitanya

For a liquid in closed vessel at constant temperature

For $K C l$ solution, $\lim_{m \to 0} \frac{Δ T_{b}}{m}$ is infinity

For a solution containing non-electrolyte solute ${(\frac{\partial T_{b}}{\partial m})}_{m \to 0} = \frac{R M T_{b}^{0}}{1000 Δ S_{V a p}} .$ Where M is G.M.W of solute in (g), $T_{b}^{0}$ -Boiling point of pure solvent.

0.9 (W/V)%NaCl is called normal saline solution.

answer is C, D.

Detailed Solution

a) In a closed vessel rate of evaporation is constant because surface area of liquid is constant

b) $Δ T_{b} = K_{b} . m . i$ at any concentration
lt $\frac{Δ T_{b}}{m} = K_{b} . i = 2 K_{b} f o r k c l$

$m \to o$
c) ${(\frac{\partial T}{\partial m})}_{m \to o} = K_{b} = \frac{M R {(T_{b}^{o})}^{2}}{1000 Δ H_{v a l}} = \frac{M R T_{b}^{o}}{1000 Δ S_{v a l}}$
