in th blånks below, show all of your work for this problem paper for later upload. Use the data provided to sketch the Born-Haber cycle for the formation of ZnCl- from Zn(s) and Cl2(g), and then calculate the lattice energy for ZNCI2(s). Carefull label each step of the cycle in your sketch. Process kJ mol 1 Bond dissociation (Cl2(g)) 242 Heat of formation (ZNCI2(s)) Heat of sublimation (Zn(s) EA (CI(g)). IE (Zn(g)) IE2 (Zn(g)) -451 131 -349 906.4 1733.3 Enter your value in the first box and an appropriate unit of measure in the second box.
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.
