Ethanol has a heat of vaporization of 38.56 kj/mol and a normal boiling point of 78.4 C.what is the vapor pressure of ethanol at 14 C?
Concepts and reason
Vapor pressure is the pressure exerted by the vapor in equilibrium with its condensed phase (liquid or solid) in a closed system at the given temperature.
The relationship between temperature and pressure is expressed with the help of the Clausius–Clapeyron equation:
Given temperature is in degree Celsius
At normal boiling point, vapor pressure is equal the atmospheric pressure.
