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.
In a Rxn , When two or more substances combine to form a new substance then this type of reaction is called combination reaction .
In a Rxn , when a compound brakes up into two or more simpler substances then this type of reaction is called decomposition reaction.
In a reaction when element takes the place of another element in a compound then this reaction is called single replacement reaction.
When two or more compounds reacts to form two or more new compounds by mutual exchange of atom or group of atoms then this type of reaction is called double replacement reaction.
