Antoine Equation

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Antoine equation is the relationship between vapor pressure and the temperature of pure substances.


Antoine equation Formula

\(\large{ log_{10} \;p = A - \frac{ B }{ C\;+\;T }  }\)   


\(\large{ p  }\) = vapor pressure

\(\large{ T  }\) = temperature

\(\large{ A, B, C  }\) = component specific constants

Solve for:

\(\large{  T =  \frac{ B }{ A\;-\; log_{10} \;p } -C }\)
