Dichloromethane heat of vaporization
WebEnthalpy of vaporization at standard conditions Data from NIST Standard Reference Database 69: NIST Chemistry WebBook The National Institute of Standards and Technology (NIST) uses its best efforts to deliver a high quality copy of the Database and to verify that the data contained therein have been selected on the basis of sound scientific ... WebThe vapor pressure of dichloromethane is measured as a function of temperature. To find the heat of vaporization a plot of natural log of vapor pressure (In P) as a function of the inverse of the temperature in kelvins (1/T) is generated. The slope of the best-fitting line is 3773 K. From this data find the heat of vaporization (AHp) in kJ/mol ...
