Problem: The boiling point of chloroform, CHCl 3, is 61.2°C. Use Trouton’s rule to estimate the enthalpy of vaporization of chloroform.

FREE Expert Solution

We are asked to use Trouton’s rule to estimate the enthalpy of vaporization of chloroform.


∆Svap = ∆HvapTb

Where: 

ΔSvap = 85 J/mol-K


Calculate ΔHvap

Given: 

ΔSvap = 85 J/mol-K

Tb = 61.2°C + 273.15 = 334.35 K
