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.
