What is Molar Enthalpy Vaporization?

The amount of energy that is needed to change a substance from liquid stage to gas stage at some constant temperature and pressure is known as molar heat vaporization. And this molar heat vaporization is represented as ΔHvap. Units of this vapor pressure at temperature are pascal.

Here is the mathematical formula that is used to calculate the molar heat vaporization is,

ΔHvap= (R x ln(p2/p1 ))/((1/T1)-(1/T2))

Where,

T1 = Initial Temperature

R = Gas constant (8.31447).

p1 =Vapour pressure at an initial temperature

T2 = Final Temperature

p2 = Vapour pressure at the final temperature
