At what temperature does ethanol boil on a day in the mountains when the barometric pressure is 547 mmHg? The heat of vaporization of ethanol is 39.3 kJ/mol and its normal boiling point is 78.3°C. (R = 8.314 J/K • mol) 4) Draw the phase diagram for a substance that liquifies with increasing pressure.

The normal boiling point of a substance is defined as the temperature at which the vapour pressure above the liquid equals the external pressure, which is one atmosphere (1 atm) or simply the temperature at which the substance boils at 1 atm. Standard pressure is 1 bar, so the standard boiling point is the temperature at which the substance boils at 1 bar. The normal boiling point for ethanol is 78.4 ∘C. Given that the heat of vaporization for ethanol...

The following paragraphs should be calculated assuming that the molar volume of Ethanol in its gaseous phase is far larger than its molar volume in either the solid or liquid phases. Moreover, one should assume that the enthalpy involved in the transition between phases does not change with temperature. Ethanol boils at 73.30 degrees Celsius at atmospheric pressure. The heat of vaporization, ΔΗvapis 39.3 kJ/mol. The melting point at atmospheric pressure is -114.10 degrees Celsius. The triple point is at...
