Reaction Enthalpy and Reaction Internal Energy

Postby Kaitlin_Reeves_1C » Sun Jan 15, 2017 1:28 pm

I'm still kind of confused on what the textbook means when it says, "The reaction enthalpy is less negative than the reaction internal energy for reactions that generate gases." Why would it always be less negative?

Because the system must use some of the energy to expand volume for the reaction products (gases).


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