Boiling Point
Feb/090
The normal boiling point of liquid ethanol is 351 K. Assuming that its molar heat of vaporization is constant?
The normal boiling point of liquid ethanol is 351 K. Assuming that its molar heat of vaporization is constant at 37.5 kJ/mol, the boiling point of C2H5OH when the external pressure is 1.33 atm is _____K.
_____The Clausius-Clapeyron equation to estimate the vapor pressure at another temperature, if the vapor pressure is known at some temperature, ...

ln(P2/P1) = - (dHvap /R) * (1/T2- 1/T1)
ln(1.33atm/1atm) = -(37500J/mole / 8.314J/moleK) * (1/T(K) - 1/351K)
SOLVE for T(K)
Basic mathematics is a prerequisite to chemistry – I just try to help you with the methodology of solving the problem.
