In this problem, an unmanned submarine is exploring the ocean floor. To relieve stress on the hull, the submarine is pressurized to 859.74 atm. Inside the submarine, someone left behind a flask of diethyl ether. The standard enthalpy of vaporization of diethyl ether is 26.52 kJ/mol and its normal boiling point (that is, the boiling point at 1 atm.) is 34.6 °C. What is the boiling point of diethyl ether in the submarine? Please state your answer in °C. °℃
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.
