Explanation:
Enthalpy of Reaction:
The Enthalpy of the system is the heat absorbed or released of the system at constant pressure , and the change of the enthalpy that results from a chemical reaction is known as the Enthalpy of Reaction.
Enthalpy of Neutralisation:
The change in the enthalpy that occors when one equivalent of an acid and one equivalent of the base undergo a neutralization reaction to form a water and salt is called Enthalpy of Neutralisation.
Enthalpy of formation:
In the most stable state i.e at (298 k) temperature and 1 bar pressure, the standard reaction enthalpy for the formation of the compound from its elements is the enthalpy of formation.
