The Antoine Equation is often used to calculate the saturation pressure of a pure species at a given temperature. Use the thermodynamic knowledge you have gained to explain what thermodynamic properties the Antoine coefficients represent.
The Antoine equation is a vapor pressure equation and describes the relation between vapor pressure and temperature for pure components. The Antoine equation is derived from the Clausius-Clapeyron relation.
The Antoine equation is a simple 3-parameter fit to experimental vapor pressures measured over a restricted temperature range:
log P = A - [B/(T+C)]
where A, B, and C are "Antoine coefficients" that vary from substance to substance
Antoine Coefficients Relate Vapor Pressure to Temperature and are having values given in mmHg
