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

$$\large{ log_{10} \;p = A - \frac{ B }{ C\;+\;T } }$$
Symbol English Metric
$$\large{ p }$$ = vapor pressure  $$\large{\frac{lbf}{in^2}}$$ $$\large{\frac{kg}{m-s^2}}$$
$$\large{ T }$$ = temperature $$\large{ F }$$ $$\large{ C}$$
$$\large{ A, B, C }$$ = component specific constants $$\large{ dimensionless}$$
