Propanol enthalpy of vaporization
WebQuantity Value Units Method Reference Comment; Δ f H° gas-283.8 ± 0.9: kJ/mol: Eqk: Connett, 1975: Heat of dehydrogenation; ALS Δ f H° gas-282.9: kJ/mol: N/A: Chao and Rossini, 1965 WebThe bonds enthalpy for an oxygen hydrogen single bond is 463 kilojoules per mole, and we multiply that by six. When we add these together, we get 5,974. So for the final standard change in enthalpy for our chemical reaction, it's positive 4,719 minus 5,974, which gives us negative 1,255 kilojoules.
