Thermochemistry

Thermochemistry is the study of the heat liberated or absorbed as a result of chemical reactions. It is a branch of thermodynamics and is used by a wide range of scientists and engineers. Thermochemistry focuses on these energy changes, particularly on the system's energy exchange with its surroundings. For example, biochemists use thermochemistry to understand bioenergetics, whereas chemical engineers apply thermochemistry to depict manufacturing plants. Chemical reactions involve the conversion of a set of substances inclusively referred to as "reactants" to a set of substances collectively referred to as "products."
