Sulfur dioxide has an enthalpy of vaporization of 24.9 kJ/mol.At 205 K,SO₂ has a vapor pressure of 30.3 mm Hg.What is the normal boiling point temperature of SO₂? (R = 8.31 J/K.mol)

Question

Quizplus · Accepted Answer

The normal boiling point is when the vapor pressure equals 760 mm Hg. Using the Clausius-Clapeyron equation, we can estimate the boiling point. Given the enthalpy of vaporization and the vapor pressure at 205 K, the calculation shows that the normal boiling point is approximately 263 K.
