The vapor pressure of ethanol is 400 mmHg at 63.5 C. Its molar enthalpy of vaporization is 39.3 K Joule/mol. What is the vapor pressure of ethanol, in mmHg, at 34.9 C? Show work.
The Clausius - Clapeyron equation predicts the temperature dependence of vapor pressures of pure liquids or solids:
ln (P/P°) =
where P is the vapor pressure, P° is a vapor pressure at a known temperature T°, H ...
