WebThe enthalpy changes of the chemical reaction HCl + Fe is -89.12 KJ/mol and this is obtained from the below mathematical calculation. The enthalpy of the reactant side is 0 KJ/mol (for Fe) and -167.15 KJ/mol (for HCl). The enthalpy values for the products are -423.42 (for FeCl2), and 0 (H2) KJ/mol.
WebEnthalpy is a state function, defined by the internal energy (E), the pressure (P) and volume (V) of a system: H = E + PV and ΔH = ΔE + Δ (PV) For enthalpy, there are no method to determine absolute values, only enthalpy changes (ΔH values) can be measured. Then it is important to have a common and well defined reference state.
