Ethanol has a vapor pressure of 7.9 x 103 Pa at 25ºC. Determine the free energy difference between ethanol in the liquid state at 25ºC and ethanol vapor at 1 bar pressure at 25ºC.
If the standard entropy of vaporization of ethanol at 25ºC is 123 J/mol.K, estimate the free energy difference between ethanol in the liquid state at 37ºC and ethanol vapor at 1 bar pressure at 37ºC.
