# 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

### Solve for:

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