Enthalpy Definition

Postby Jasmine 2C » Mon Feb 10, 2020 1:23 am

When we talk about enthalpy in any aspect (standard rxn enthalpy, standard enthalpy formation, change in enthalpy, etc), is it always defined as the amount of heat released or absorbed at constant pressure?

Yes, enthalpy will only equal heat of a reaction at constant pressure.

Enthalpy would be defined as the study of heat absorbed or released during chemical reactions and physical changes.

Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
