ClausiusClapeyron Equation is given as: P vap = vapor pressure H vap = enthalpy of vaporization, J/mol R = 8.3145 J/Kmol T = temperature

1. Clausius–Clapeyron Equation is given as:

 P_vap = vapor pressure

                        ΔH_vap = enthalpy of vaporization, J/mol

                        R = 8.3145 J/K·mol

                        T = temperature (in Kelvin)

 

The vapor pressure of water at 25°C is 23.8torr, and the heat of vaporization of water at 25°C is 43.9 kJ/mol. Calculate the vapor pressure of water at 65°C. Would the result change if you were to use  Pascal instead of Torricelli for the pressure unit?
