Enthalpy of Formation. The (molar) enthalpy of formation is the heat released ( ) or absorbed ( ) in a chemical reaction at constant pressure when simple substances combine into a more complex substance. At standard conditions of pressure and temperature (1 atm and 298 K), it is denoted . For elements in their standard states, .
Answer. The enthalpy change for a formation reaction is called the enthalpy of formationThe enthalpy change for a formation reaction; denoted ÎHf. and is given the symbol Î´ H f. The subscript f is the clue that the reaction of interest is a formation reaction.olution. 1  In this reaction, two moles of product are produced, so this is not a proper formation reaction. 2  In this reaction, one mole of a substance is produced from its elements in their standard states, so this is a proper formation reaction.
