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.
Introduction
Attractive forces in chemistry refer to the interactions between molecules that cause them to bind together and form compounds. The two most common types of attractive forces are the ionic bond, which occurs when two oppositely charged ions attract each other, and the covalent bond, which occurs when two atoms share electrons. Hydrogen bonds are also an important type of attractive force, which occur when hydrogen atoms form weak bonds between molecules. In addition to these attractive forces, van der Waals forces, which are caused by the dipole moments of molecules, also contribute to the binding between molecules.
