Boiling Point Concepts

Clausius-Clapeyron Equation

ln(P₂/P₁) = -(ΔHvap/R) × (1/T₂ - 1/T₁)

  • • P₁, P₂ = Vapor pressures
  • • T₁, T₂ = Absolute temperatures
  • • ΔHvap = Heat of vaporization
  • • R = Gas constant (8.314 J/mol·K)

Antoine Equation

log₁₀(P) = A - B/(C + T)

  • • P = Vapor pressure (mmHg)
  • • T = Temperature (°C)
  • • A, B, C = Substance-specific constants
  • • Widely used for organic compounds
