Concept explainers

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.

For this demonstration to the CEO, we're going to calculate the change in enthalpy, AH, for the
combustion of 4 compounds: methane (CH4), ethane (C₂H6), propane (C3H8), and ethanol
(C₂H5OH).

For each compound, complete the following steps:
a) Write a complete, balanced combustion equation using Lewis structures for all
species. An example for methane is shown below.
b) Make a list of all the bonds that are broken and formed during the reaction (see
also example below).
c) Calculate AH in kJ/mol using the equation above.
d) Calculate the AH in kJ/g.
