Bond energy
Energy.
Heat
energy released by the reaction or energy absorbed.
no
Yes, heat is often released or absorbed during a chemical reaction. This is because chemical reactions involve the breaking and formation of chemical bonds, and the energy difference between these bonds is released or absorbed in the form of heat.
In a chemical reaction, energy can be both absorbed and released. When energy is absorbed, it is required to break bonds in the reactants, and when it is released, it is due to the formation of new bonds in the products. Additionally, atoms and molecules can also be absorbed and released in various forms during a chemical reaction.
Energy.
Heat
energy released by the reaction or energy absorbed.
no
no
energy is released or absorbed.
Depending on the particular chemical reaction, energy may be either released or absorbed.
The unit of energy commonly used to identify the amount of energy released or absorbed by a chemical reaction is the kilojoule (kJ).
The enthalpy of reaction measures the amount of heat absorbed or released during a chemical reaction at constant pressure. It indicates whether a reaction is exothermic (heat is released) or endothermic (heat is absorbed).
no
Enthalpy is the total heat content of a system, including both heat absorbed and released during a reaction. Heat of reaction specifically refers to the heat released or absorbed when a specific chemical reaction occurs.
