Elevation in the boiling point for 1 molal solution of glucose is 2K. The depression in the freezing point of 2 molal solutions of glucose in the same solvent is 2K. The relation between K_band K_fis

Options:

Answer:

Solution:

$Δ T_{b} = K_{b} m$
$K_{b} = \frac{Δ T_{b}}{m} = \frac{2}{1} = 2$
…(i)
$Δ T_{f} = K_{f} m$
$K_{f} = \frac{Δ T_{f}}{m} = \frac{2}{2} = 1$
…(ii)
$\Rightarrow \frac{K_{b}}{K_{f}} = 2$
$\Rightarrow K_{b} = 2 K_{f}$
