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.
Question
Transcribed Image Text:Enthalpy of Combustion (AH):
1. An alcohol is burned, and the heat is transferred to a large calorimeter that contains 3.0 kg of water. This
combustion used up 0.285 moles of the alcohol and the temperature of the water to rose by 36.00°C. What is
the enthalpy of combustion (AHC) of this alcohol in kJ/mol? (Remember that 1 kg = 1000 g)
2. When 1.20 g of hexane (C6H₁4) are burned, the temperature of 250.0 g of water is raised by 56.0°C. What is the
enthalpy of combustion (AHC) of hexane in kJ/mol?
3. Use the following experimental data to determine the enthalpy of combustion of propanol (C3H₂OH) in kJ/mol
Mass of water = 200.00 g
Initial water temperature = 18.2°C
Final water temperature = 38.6°C
Initial mass of alcohol lamp = 185.51 g
Final mass of alcohol lamp = 184.56 g
