The Endothermic and Exothermic Process To understand the mechanism of endothermic and exothermic reactions, let us first look into the concept of enthalpy. Enthalpy Enthalpy is a fundamental thermodynamic quantity that measures the heat content of a system. It is generally represented by H and being...
a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+Δ
Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).Examples of Endothermic and Exothermic Processes Photosynthesis is an example of an endothermic chemical reaction. In this process, plants use the energy from the sun to convert ...

Exothermic reactions occur when the forming of a chemical bond releases energy therefore creating an exothermic process (Kentchemistry.com, 2015). An exothermic reaction has a negative deltaH, because the enthalpy of the products is lower than the enthalpy of the reactants of the system (Chem...
