Question

Relation between ebullioscopic constant and latent heat of vaporisation

Answer 1

The Relation between the Electroscopic contact and latent heat of vaporization is given below,

     

  $Kb = \frac{ RT^{2} _0}{1000L_v}$

where, Kb is the Ebullioscopic constant, lv is the latent heat of vaporization per gram of the solvent , R is the universal gas Constant or you can also say it here as solution constant.

We know that lv = Δvap.H/M

Put in this Equation, we will get,

  $Kb = \frac{ MRT^{2} _0}{1000H}$
