Respuesta :
The name and symbol of the thermodynamic quantity that represents the heat absorbed or liberated in a chemical reaction at constant pressure will be enthalpy represented by ΔH.
A thermodynamic system's enthalpy, which is one of its properties, is calculated by adding the system's internal energy to the product of its pressure as well as volume. It refers to a state function that would be conveniently provided mostly by a substantial ambient atmosphere and is utilized in several investigations in chemical, biological, as well as physical systems at such constant pressure.
Because it tells how much heat seems to be there in a system, enthalpy is significant (energy). Heat is crucial because it allows us to produce useful work. In terms of a chemical process, an enthalpy shift reveals how much enthalpy was gained or lost. Enthalpy is the system's thermal energy.
Therefore, thermodynamic quantity that represents the heat absorbed or liberated in a chemical reaction at constant pressure is enthalpy represented by ΔH.
