Consider an iron blast furnace operation. If an iron ore consisting of separate Fe,O; and Fe;O4 is smelted, and the products contain 55 kg FeQ in slag and 832 kg Fe in pig iron, what are the chemical reactions and corresponding temperatures involved if the total Fe in Fe,O3 and total Fe in Fe;O4 are equal? What are the weights of Fe;O; and Fe;04? Note: The iron oxides are reduced by CO. Input Output Slag Pig iron 55 kg FeQ 832 kg Fe Iron ore Fe203 Fe304 You may create a sample calculation to justify your answer.
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.
