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.
Q3- Only answer d and e
![South Africa is one of the world's largest iron ore producers. From the reaction below, answer
the following questions based on the iron ore extraction:
Fe:Og6) + Ce) → Feg) + CO29)
a) Give the correct chemistry name for Fe2O3 and CO2.
b) If 9888.8g of Fe2O3 and 1258.2g of C react, determine which reagent is the limiting
reagent/reactant of the reaction.
c) Calculate theoretical yield of the reaction.
d) If the foreman on site obtained 6.12 kg of Fe, for the reaction described in b) above,
what is the % yield of the reaction?
e) The product Fe is in liquid format. Do you think this is correct or not and justify why you
think so?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F43e0f925-1039-47ac-b1a0-0b939fac7262%2F1f6c51fa-856c-4f3c-ab92-56ad50113ddc%2Fauyscns_processed.png&w=3840&q=75)
