Energy, change in reaction

The energy change in reaction (1) is called the first ionization energy and the energy associated with reaction (2) is the second ionization energy. We symbolize the two processes as I( ) and 1(2) respectively. 

Similarly, Metallurgical Thermodynamics is that part of thermodynamics, which deals with energy changes in reactions involving metals and their compounds. Many look upon it as the High-Temperature Chemical Thermodynamics. ...
