Net standard state enthalpy of Combustion at 298.15K

• Definition

  Heat of combustion ΔH_c(298.15K) is the calorie generated when a substance is completely combusted in the standard state of 298.15K and 1bar, reacting with oxygen.
  The general formula of reactants and products in the standard state at T=298.15K:
  ΔH_f(298.15K) =-393.78N_C-121.00(N_H -N_x )-271.81N_F-97.37N_cl-36.26N_br+24.81N_I-297.26N_S- ΔH_c(298.15K)

  Combustion product : CO₂(g), F₂(g),Cl₂(g), Br₂(g), I₂(g), SO₂(g), N₂(g), H₃PO₄(s), H₂O(g), SiO₂(cr)/CuO,H₂SO₄

• Estimation Method

  - MolInstincts: The Property value is estimated by the thermodynamic relationship with other properties. The estimated value is finally determined after manual inspection.
