# 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:

$$\large{ p }$$ = vapor pressure

$$\large{ T }$$ = temperature

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

Find:

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