Webb15 maj 2024 · For any solvent, the vapor pressure VP can be calculated at temperature T using the three Antoine Constants, AA, AB, AC via: log10VP = AA-AB/ (T+AC) From this equation we automatically get VP 25. The BPt is found from the value of T that gives VP=1 atm. And the RER (defined at 25°C) is basically 100.
