Web1 mrt. 2024 · XY (g) → X (g) + Y (g) ΔH° (298 K) = Dx−y. Any bond enthalpy formula is given at 298 K by convention to standardize the equation. This is approximately room temperature, equal to 25 °C or 77 °F. In reality, the reaction above is most often hypothetical, as most molecules do not exist as monatomic gases at 298 K. Uses Antoine's equation: log 10 P m m H g = 7.87863 − 1473.11 230.0 + T {\displaystyle \scriptstyle \log _ {10} {P_ {mmHg}}=7.87863- {\frac {1473.11} {230.0+T}}} from Lange's Handbook of Chemistry 10th ed.
