Given the heat of vaporization of benzene as 30.8 kJ/mol and the vapor pressure = 92 mm Hg at 25°C. Calculate the vapor pressure of benzene at 75°C.
Two students measured the vapor pressure of water at seven temperatures between 50.0°C and 80.0°C and made a graph of the natural logarithm of the vapor pressure versus the reciprocal temperature. Then the students fit their data to a straight line equation (R2 - 0.997): y = 13.66 - 5076.3x. From this data, calculate the enthalpy of vaporization for water.
