What is NOT true about the reaction below? 2N₂ + 3H₂2NH3 A B C D The reaction 2N2 + 3H₂ → 2NH3 occurs. The reaction 2N2 + 3H₂2NH3 occurs. The reaction can be a synthesis reaction one way and a decomposition reaction the other way. The reaction can be a single-replacement one way and a double-replacement reaction the other way.
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.
