The heat of reaction, also known as enthalpy change, is the amount of heat absorbed or released during a chemical reaction at constant pressure. It provides insight into the energy dynamics of a reaction, indicating whether the process is exothermic or endothermic.

Enthalpy change is the heat absorbed or released during a chemical reaction at constant pressure, reflecting the difference in enthalpy between reactants and products. It is a crucial indicator in thermodynamics, determining whether a reaction is endothermic or exothermic and influencing reaction feasibility and spontaneity.

A chemical reaction is a process where substances, known as reactants, are transformed into different substances, called products, through the breaking and forming of chemical bonds. This transformation involves changes in energy and is governed by the principles of conservation of mass and energy.

Energy dynamics involves the study of how energy is transferred and transformed within and between systems, encompassing both physical and biological processes. It is crucial for understanding phenomena in fields such as thermodynamics, ecology, and engineering, where energy efficiency and sustainability are key considerations.

energy dynamics

An exothermic process is a chemical reaction or physical change that releases energy in the form of heat to its surroundings, resulting in an increase in the temperature of the environment. This type of process is characterized by a negative change in enthalpy, indicating that the energy of the products is lower than that of the reactants.

Exothermic Process

An endothermic process is a chemical reaction or physical change that absorbs energy from its surroundings, typically in the form of heat, resulting in a decrease in the temperature of the environment. These processes are characterized by a positive change in enthalpy, indicating that the system has gained energy from the surroundings.
