The standard enthalpy of atomization of an element is the energy required to convert one mole of an element in its most stable form at 25 °C to one mole of kJ monoatomic gas. Given that the standard enthalpy of atomization for sodium is 107.5 calculate the energy in kilojoules required to convert 2.77 mol of mol' sodium metal at 25 °C to 2.77 mol of gaseous Na+ ions. [The ionization energy of Na (g) is 495.9 significant digits. kJ mol .] Be sure your answer has the correct number of kJ x10
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
