What is an enthalpy change?

Accepted Answer

Enthalpy change refers to the amount of heat absorbed or released during a chemical reaction at constant pressure. It's a key concept in thermodynamics, representing the change in the total energy of a system. A positive enthalpy change indicates an endothermic reaction (heat absorbed), while a negative enthalpy change signifies an exothermic reaction (heat released).
