1. TH202 : Ebulliometric Determination of
Vapor Pressures

2. Theory: clusius Clapeyron Equation
Aim:
Determination of vapor pressures of pure substance at different temperatures.
Determination of enthalpy of vaporization and correlation constants in the vapor pressure equation
Theory: clusius Clapeyron Equation
Where,
At low pressures ≤1 atm, ZV > ZL and ZV≈1, therefore, ΔZv≈1
Therefore,

3. Determine the boiling points of a pure substance (T) at various
pressures (P) ranging from 760 mm Hg to100 mm Hg
Where, A = intercept and B = slope = -ΔHv/R
