Although the laws of thermodynamics can be a little tricky to follow the first law of thermodynamics is a simple relationship between the work done heat added and the change in internal energy of a substance.
A neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. Why is enthalpy useful. According to the definition of enthalpy of neutralization chem libretexts the standard enthalpy change of neutralization is the enthalpy change when solutions of an acid and an alkali react together under standard conditions to produce 1 mole of water.
Enthalpy is important because it informs us how much heat is in a system energy. Recommended Videos Standard Enthalpy of Formation.
