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, .
â¢ ïG = ïH-TïS (ïG in units of kJ/mol) ïµ ïH is enthalpy (kJ/mol), T is temperature (K), ïS is change in entropy (J/molÂ·K) â¢ In any spontaneous process (constant T and P), the free energy of the system always decreases! Spontaneity is determined by both the enthalpy and entropy of a reaction. Enthalpy, Entropy and Spontaneity Nature tends toward state of lower energy. ï· Many spontaneous processes are exothermic (e.g. combustion reactions have ï ï Nature tends to become more disordered or random.
