Methanol has been proposed for use in fuel cells for automotive applications. The vapor pressure for methanol (CH₃OH) was measured to be 4.02 and 352 kPa at 273 K and 373 K, repectively. Use these data to estimate the enthalpy of vaporization (kJ/kg) of methanol. Compare your result with the actual value (from the NIST resources or other source) at the average of the two temperatures.
