# 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

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

### Where:

 Units 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 dimensionless
