At standard temp and pressure (which is sea level pressure of about 1 atm and 25°C) we can assume the following relationship- 24,000 mL of gas = 1 mole of gas molecules. In fermentation, we can also assume that the ratio of gas molecules and ATP are equal to each other, ie 1 mole of gas = 1 mole of ATP. %3! If we were to produce 12.0 mL of gas in a fermentation reaction, how many moles of ATP will we have produced in the fermentation process?
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.
