ChemistryChemistry & Chemical ReactivityThe equation for the straight line using the given data has to be written. Concept Introduction: Clausius-Clapeyron equation: ln P = − ( Δ vap H 0 RT ) + C From this relationship we can calculate the molar enthalpy of vaporization by knowing the corresponding temperature and pressure values. If we have pressures at two different temperatures, then enthalpy of vaporization can be calculated by ln P 2 p 1 = - Δ vap H 0 R [ 1 T 2 - 1 T 1 ] Boiling point of a liquid: The temperature at which external pressure and vapour pressure of the liquid become same. Normal boiling point: When the external pressure is 760 mm Hg we can call it as normal boiling point.Start your trial now! First week only $4.99!*arrow_forward*
