45. What is the relationship between the eubllioscopic constant and the elevation in boiling point of the solution?

the elevation of boiling point (ΔTb) is directly proportional to the molal concentration of
the solute in a solution. Thus
ΔTb ∝ m 
or ΔTb = K_bm 
Here m (molality) is the number of moles of solute dissolved in 1 kg
of solvent and the constant of proportionality, Kb is called Boiling Point
Elevation Constant or Molal Elevation Constant (Ebullioscopic
Constant). The unit of K_b is K kg mol-1.
