\log_{10} p = A-\frac{B}{C+T}.

where p is the vapour pressure, T is temperature and A, B and C are component-specific constants.

The Antoine equation can also be transformed in a temperature-explicit form with simple algebraic manipulations:

T = \frac{B}{A-\log_{10}\, p} - C

Example

Calculate the vapor pressure of oxygen (O2) at –178.24 C.

Substitution of the Antoine coefficients from the table and temperature into the equation for vapor

pressure yields:

log10 P = 6.83706 – 339.2095/(-178.24 + 268.70) = 3.08738

P = 103.08738 = 1222.87 mm Hg
