From the following information, calculate the bond energy of Cl2(g). Write out the Born Haber cycle for the entire process by hand and show your work for the calculation of the bond energy. Make sure you include all states of matter. Upload the picture of your work and answer to this document. IE, + Heat of sublimation of cadmium = 102 kJ IE, of cadmium = 2490 kJ Electron affinity of chlorine = -342 kJ Heat of formation of cadmium chloride = -396 kJ Lattice energy of cadmium chloride = -2540 kJ
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.
