Definitions:

Enthalpy Reaction

A thermodynamic quantity equivalent to the total heat content of a system, representing the sum of its internal energy and the product of its pressure and volume, especially useful in the study of heat exchange in chemical reactions.

Electrochemical Reaction

A chemical reaction that involves the transfer of electrons from one species to another, often associated with electricity.

Exergonic

Describing a chemical reaction that releases energy to its surroundings, typically in the form of heat or work.

Endergonic

Endergonic refers to a chemical reaction where energy is absorbed from the surroundings, generally requiring an input of energy to proceed.
