Can someone please explain the difference between standard reaction enthalpy and standard enthalpy of formation?
Standard reaction enthalpy (∆H°) is the ∆H that accompanies a change in system due to a chemical reaction where all reactants and products are in their standard states. Standard enthalpy of formation (∆H°f) is the ∆H during the formation of 1 mole of the substance, with all substances in the reaction in their standard states. Standard conditions are 273K, 100 kPa or 1 bar.
Standard reaction enthalpy is the enthalpy that occurs in a reaction and the SE of formation is during the formation of 1 mole of something
