10. You're preparing for a camping trip. you see two different stoves you can pack for your trip to do all your cooking. Which fuel would you prefer to carry? One stove uses fuel propane. The other stove uses naphtha (hexane) fuel. Start by writing a balanced combustion equation for both of these reactions. Use either standard enthalpies of formation or bond energies to determine the enthalpy changes for the combustion of these two fuels. Then suggest which stove, the one that uses propane or the one that uses naphtha, would you recommend to pack for your camping trip? Explain. (You may need more space for your response).
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.
