The Toyota Mirai is a hydrogen fuel cell car. It creates electrical energy through the reaction of hydrogen and oxygen to make water H₂(g) + 1/2O₂(g) → H₂O(l) There is the following data Compound H₂ 0₂ H₂O AH°f (kJ/mol) 19 0 0 -285.93 S° (J/mol-K) 130.6 205.0 69.9 What is the value of AG° per mole of H₂O made in this reaction in kJ/mol at 25.0°C. If the answer is -123.3 kJ/mol just type -123.3 as Canvas won't understand the units
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.
