What is Thermochemistry?
The study of thermochemistry examines the heat energy involved in chemical reactions and/or phase transitions like melting and boiling. Energy can be released or absorbed during a reaction or phase change. Thermochemistry focuses on the heat-based energy transfer between a system and its surroundings. In order to forecast the quantities of reactants and products throughout a specific reaction, thermochemistry is helpful. It is also used to foretell whether a reaction will be spontaneous or non-spontaneous, favourable or unfavourable, in conjunction with entropy determinations. While exothermic reactions discharge heat, endothermic reactions absorb heat. The concepts of thermodynamics and the idea of energy in form of chemical bonds are combined in the field of thermochemistry.
