Question: what is a standard molar enthalpy?
Answer: 2.2. 2 Standard Enthalpy of Formation The standard molar enthalpy of formation of a compound is defined as the enthalpy of formation of 1.0 mol of the pure compound in its stable state from the pure elements in their stable states at P = 1.0 bar at constant temperature. So, for example, ΔH298.15o of the reaction in Eq.
