The Clausius-Clapeyron Equation establishes a quantitative relationship between vapor pressure and temperature.
Concept #1: Understanding the Clasius-Clapeyron Equation
Vapor Pressure looks at the equilibrium established between vaporization and condensation. By using the Clasius-Clapeyron equation, the enthalpy of vaporization can be determined.
Example #1: The heat of vaporization (ΔHvap) of water is 40.3 kJ/mol at its normal boiling point at 100oC. What is the vapor pressure (in mmHg) of water at 60oC?
